I’m Being Overworked by My Employer – What Should I Do?

In our society, it can often feel like the only choices are working yourself to the bone, or death. In some cases, that may even be true – with all the inequalities people face in the workplace, it is hard not to find yourself in a position where you go to work, come home, sleep, then wake up and repeat. You have no time for anything else. Your constant exhaustion is not a figment of your imagination – you are being overworked. In times like this, you might feel powerless. You need money to live comfortably, and you can only make money when you work. You do not want to lose your job and be faced with the daunting task of trying to find a new work in this economy. However, you do not have to take it lying down. There are things you can do to combat overworking in the workplace. 1. Job Search If you truly feel you are being worked to the bone and do not see a light at the end of the tunnel, the first step is to consider searching for a job while you are still employed with your current job. If you find something suited to your skillset that sounds more flexible, then apply there so that you will not need to worry about not having work at any point. Find a field that works with your knowledge, but tends to have a high satisfaction level. For instance, home health agencies overworking their employees is a common occurrence. If you have any medical skills and wish to stay in that field, consider looking elsewhere. There is a dire need for medical services – you may be able to find something that works better for you. 2. Speak to Your Manager/Supervisor Often, you might feel like just a number to your employee. The sad truth is that that is how it is at some companies. However, before taking drastic measures, talking to your supervisor may be the first step to lessening your workload and getting yourself a chance to breathe. All managers are different, but if you speak with a superior about feeling exhausted or overwhelmed, they may be able to re-designate workloads so you can take a breath without sacrificing your job. 3. Make Lists Prioritize your work. This is another “first step” after you have realized how much your work is affecting you. If you can list everything you need to do in order of importance, you will have the makings of a plan on how to accomplish your goals in a timely manner that is not overwhelming. If you have multiple projects due all at once, that is a sure sign to speak to your supervisor – you should not have endless piles of work on your shoulders simply because you are good at your job. 4. Learn to Say No You need to know your limits. Even if you feel like just a number, you have to know when you are near your breaking point. Sometimes, setting boundaries and protecting yourself means that you just have to say “no” when you are asked to take on more than is reasonable. If you have multiple supervisors, talk to the one(s) you are most comfortable with, or the ones that seem to have the best reputation. Tell them about how you are feeling, and if new projects fall on your lap that feels out of your control, talk to them before you even start. It will give them a chance to reassign if they can, and it will give you one less thing to focus on. 5. Consider Legal Action If you feel like you are being worked beyond what you're agreed upon duties are, or you are constantly forced to work overtime without compensation, you may have grounds for legal action. This is, of course, the last case scenario, as it will cost money and damage to the reputation of the workplace. However, if you truly feel it is warranted, it is an option to consider. Overall, there are a few things you can do when you feel you are being overworked. Start small, like prioritizing and talking to managers, and if no change occurs, then it may be time for more. Remember: you are more than a number, you are a human being who deserves respect and a safe work environment.

The Art of Answering Hard Interview Questions

Navigating hard interview questions can be a challenge most job seekers face. Especially when these tough questions do not have a correct answer! Knowing how to answer tricky questions while maintaining professionalism can set you apart. Below, we break down some of the difficult interview questions asked during interviews. Then, offer strategies for crafting solid responses and outline the professional etiquette necessary to leave that long-lasting positive impression. #Hard Question 1 - “Tell me about yourself.” This is more of a statement than a question, but it's the opening question so many people have trouble with. It's the simplest thing imaginable, yet people seem to need to learn how to do it. The trick here is that you don’t have to tell your entire life story; in fact, please don’t. Stick to basic information and then cut to educational and professional qualifications, which can help you in the job role you are interviewing for. #Hard Question 2 - “What are Your Weaknesses?” I know that everyone says not to do this. You know be all quirky and make a witty joke! Not very ideal interview skills. But interviewers now really appreciate quick wits! I recently, however, did it in a big interview. My answer to this question was: "Since I am assuming there is a finite amount of time for each applicant, and there are many qualified applications, my biggest weakness would be running out of time to tell you how fantastic I am." It worked, too. One of the serious ones even had a light hint of a grin on her face! It’s a bit of a trap, but interviewers just want to know that you’re self-aware and working on it. Nobody’s perfect, so feel free to use a real one. Just make sure it’s not a disqualifying one. For example, do not give stupid and vague answers like "I am a perfectionist, and since I always tend to give a perfect copy of my work, it affects my mental health." Derailing mental health because of crippling OCD is a serious condition, and you shouldn't be using this to put yourself on a pedestal! #Hard Question 3 - “How Are You Working on Your Weaknesses?” Among the hard interview questions, weaknesses will take a good chunk of it. If you answer the previous question well, this question will inevitably come your way! Example: “I’m trying to improve my presentation skills. I’ve been joining Toastmasters and practicing my speaking.” “I am currently focused on improving my communication skills, particularly my public speaking. I am working on being a more persuasive speaker so that I can do well in this class and professional presentations. One area that I believe would help me be more effective is learning to use visual aids to give better presentations.” Give detailed steps that you are taking to turn your weaknesses into strengths. #Hard Question 4 - “Why Our Company?” Let me get this straight! You are fooling no one by implying this is the only interview you have lined up. This is one of the reasons why you need to be professional and do thorough research about the company who is interviewing you. It begins with tailoring your resume, and cover letter based on the company's job role. Next, knowing about the job role and what they are looking for. Among all the hard interview questions, this is particularly a test of how well you’ve researched the company. Interviewers want to see genuine interest in the role and organization. First, state the company’s values, culture, or projects that match your interests and goals. Second, communicate what you can contribute to their team. Pro Tip: Be detailed! Don’t just say, “I like the company’s mission.” Explain what specifically appeals to you about their objectives/goals and why you are passionate about what they do. #Hard Question 5 - “Why Should We Hire You?” This is your chance to tell them why they should take a chance on you. Share with them your top strengths that would be compatible with the job posting. Think of it as a quick elevator pitch. (Pro interview tip: You should always have an elevator pitch about yourself ready). As if you entered an elevator with the CEO of your dream company – 30 seconds – how would you sell yourself to him/her? You want to make it clear that YOUR skills, experience, and confidence make you unmistakably perfect for this job or this company! “I have been in customer service for five years and have never missed my performance goals. I’m looking forward to using my abilities in your company to help customer satisfaction.” #Hard Question 6 - “Where do you see yourself in 5 years?” This question is to ensure two things: Whether you are committed to the position you are getting. Do you have the zeal to do better and strive for a promotion in the foreseeable future? Most interviewers are trying to determine if you plan to stay with the company or are likely to leave as soon as you find a better opportunity. They also want to understand your level of ambition. Think of how your goals would align with the position and company you’re applying for and discuss how you’d like to grow within the company. Pro Tip: "Do not mention other roles or industries; talk about how you can progress within the company that is interviewing you." #Hard Question 7 - “Describe a time you dealt with a difficult situation.” Every corporation has its own difficulties to deal with. However, if this is your first job, you can very well draw conclusions from your academic challenges. Pro Tip: They do not want to know whether you handled a team of teams and dealt with a difficult situation all by yourself. However, they will want to know whether you have the strength and resilience to deal with any difficult situation alone. This question tests your problem-solving and stress-handling abilities. Use the STAR (Situation, Task, Action, Result) method to structure your response. For example, pick an example from your professional life, describe the difficulty, detail what you did to address it, and emphasize the positive result. "I had a client that was upset over something that wasn’t communicated correctly. I fixed it immediately and told the client we wouldn’t make mistakes like that going forward. Plus, I offered them certain gifts as compensation. The client was happy with the results. It just takes a little bit of hearing the other side to ensure you retain an angry customer." #Hard Question 8 - “Can you explain the gap in your employment?” Most people have a time in their employment history when they weren’t working for one reason or another, whether it be for personal reasons, going back to school or some other endeavor. Therefore, these tough interview questions about gap years can make almost anyone nervous! The best way to answer concerns over an employment gap is honestly. However, ensure to mention things you did that will show how and why you were still productive during that time. Any courses you did, or how you upskilled yourself in this gap year, or work on projects will help strengthen your case. Pro Tip: Keep it positive. You should be honest, but this is not an opportunity for you to vent about what annoys you at work. #Hard Question 9 - "What motivates you?" Your answer should be related to the position you’re applying for, so think about what you’re most excited to do at this job and why—whether it’s reaching a personal goal or being able to help other people, for example—and explain how that relates back to your role at the company. #Hard Question 9 - “What is your greatest professional achievement?” This question is a great chance to subtly brag about yourself, but also remember that the interviewer wants strengths relative to the position, not in general. For example, if you are applying for a management-level position and have managed teams in the past, explain how many people you have managed, the largest team size you have led, and any notable achievements as a manager. "I led a team who achieved an almost 20% boost in sales in just six months thanks to our new customer engagement strategy." Pro Tip: Whenever possible - quantify. Numbers always add a layer of credibility. Plus, try to keep your face and tone professional whenever you say such a thing. It shouldn't come out like you are bragging, but at the same time, you should be proud of your achievements and not downplay it." #Hard Question 10 - "Do you have any questions for us?" Don’t say “no.” This is your opportunity to demonstrate that you’re genuinely interested in the position, so ask a good question — or several. Inquire about things like company culture, team dynamics, or growth opportunities within the organization. However, save questions about salary and benefits for later in the process. Especially if you have a few interviews to crack, always ask about the salary in the final round. Do not worry; you can always negotiate, and even if the salary is not up to the mark, you cannot always take that position. Pro Tip: Come prepared with a list of questions to ask that demonstrates you’ve done your homework. Here is a list of unique interview questions to ask the employer! Professional Etiquette Tips for Interviews Now that you know about the hard interview questions and the answers that are close to the appropriate ones, here are a few more items to remember! 1. Being Punctual is Non-Negotiable Being punctual should be a non-negotiable when it comes to attending interviews. Arrive on Time. It may sound simple, but arriving on time for an interview is critical. In fact, 10-15 minutes early is probably the best arrival time. However, not more than that, you wouldn't want to seem too eager or nervous. 2. Your Posture Speaks a Lot Your non-verbal signals reveal a lot about yourself. Sit with your back straight, make eye contact, and smile with a firm handshake. Don’t hold your arms or fidget, as the interviewer might take it wrongly as a sign of apprehension or disinterest. Instead, slightly lean forward and nod to show that you are engaged. 3. Listen – Do not Just Jump to Answering The art of active listening is a must when giving an interview! Allow the interviewer to complete his/her thoughts and then answer the question. It helps you to frame your response in a better way and reflects your genuineness in the conversation. 4. Politeness is Given Being polite also has a long way to go. Start and finish the interview by thanking your interviewer for their time. And send a follow-up thank-you email later too; to remind them how interested you are in this job. 5. Dress code If you’re unsure what to wear, it’s better to be overdressed than underdressed. Even if you’re not sure of the company culture, dressing a little more formally will give the impression that you take this opportunity seriously. Plus, who doesn’t look great dressed up? Look at some of the best interview attire for men. Why a Good Cover Letter Matters as the Final Touch? A strong cover letter for a resume can be the difference between standing out or blending in with the pile of applications. It’s your chance to showcase why you’re a perfect fit for the role beyond what’s listed in your resume. A great cover letter adds a personal touch, offering data for your qualifications and highlighting specific achievements that match the company’s needs. Plus, it’s an excellent opportunity to demonstrate your communication skills. Make it concise, focused, and tailored for each job. This effort shows you’re genuinely invested in the role. Confidence is Everything! Mastering hard interview questions and maintaining professional etiquette is essential for landing your dream job. With the right preparation, you can confidently handle even the toughest questions. Always remember to follow up after your interview, and don't overlook the importance of your cover letter as the final touch. These small details will make a big difference in setting you apart from other candidates and getting you closer to that job offer.

Top 7 Reasons the Medical Field Will Always Be In Demand

Humans have always had to face illness, from the dawn of civilization onward to today. We’ve faced plague, chronic illness, sudden disease, injury, and more at the hands of other humans and natural processes. The unfortunate reality for us is that our mortality also means facing some of life’s most difficult challenges, and facing sickness is something none of us want to do. The healthcare field exists to help with those illnesses, providing treatment, recovery, and support. Why will the medical field always be in demand? 1. Unfortunately, Sickness Will Always Be A Reality: Some of the oldest diseases to plague mankind date back to about 8,000 B.C.E., long before humans ever stepped foot on the moon or discovered antibiotics. As long as there have been microbes and animals for them to attach to, there has been illness. The unfortunate truth for us is that illness and disease will always be a part of human life, short of a sci-fi-esque superpower that prevents all illnesses. Where there is an illness, there needs to be care—and our healthcare providers are there to provide it. There will always be jobs in the field. Even during economic downturns, people still get sick. New jobs open up as technology advances and healthcare techniques evolve. Even as things like AI and machine learning come into play, you simply can’t replace the people that operate on the frontlines of our healthcare industry, providing more than just care and medical knowledge to patients. 2. It Takes A Certain Kind Of Person To Do Specific Jobs In The Field: The truth about working in healthcare is that it’s simply not for everyone. Some jobs involve long hours, stressful environments, and can even expose you to potentially harmful conditions. Let’s take our frontline workers during the pandemic, for example. We’ve all seen the pictures on social media and in the news of healthcare workers with marks on their faces from wearing masks for hours on end, their tired eyes looking at us mournfully to please follow COVID guidelines. Working in such an environment isn’t everyone’s cup of tea. It takes a certain kind of compassion and empathy to put yourself at risk to help others. That’s not to say there’s anything wrong with not wanting to do that—it’s just not something that everyone can be happy about doing on a daily basis. This does create a certain demand, however. Since not just anyone can jump into scrubs and work a 12-hour shift in a hospital, there are often openings in the field. Not every job will require such dedication and personal risk, but you get the point. 3. The Industry Is Always Growing And Changing: As we learn to better understand the human body, disease, and illness, the healthcare industry evolves and changes. We’ve come a long way from the Greek theory of four humors, but that doesn’t mean we know everything, or will ever know everything. What it does mean is that there will always be new kinds of jobs added to the healthcare field as new technology and methods emerge. Even as AI becomes more prevalent in a number of industries, something like healthcare needs people. AI simply can’t match the caring, compassionate nature of an actual person providing care to someone who’s sick. It can’t console a family when their loved one is diagnosed with cancer. It can’t hold their hand while they undergo a serious operation. The bottom line is that the industry will always change and evolve, adding new jobs and techniques, but it will always need people. People are the core of the healthcare industry. 4. Training Is Becoming More Streamlined: The industry becomes more and more competitive as training programs become more streamlined. Now, you can complete training for certain positions entirely online. This leaves more flexibility and inclusivity in the industry, but can also mean more competition. You can obtain a medical billing and coding certification online in just under a year, setting you up to enter the field very quickly. But remember that others are also taking that path, potentially blocking you from your career if you’re not doing something that helps you stand out. 5. Not Every Job Requires A Degree: When you think of healthcare, you automatically think of doctors and nurses in scrubs and white lab coats, but the truth is, there are thousands of healthcare jobs out there, and many don’t require a degree. You can become a medical biller/coder/pharmacy tech or even a dental assistant without a degree. You’ll need to get certified and complete a training program, but you won’t be in a college setting for years on end, and you won’t be thousands in debt at the end of the program. A course in Basic Life Support (BLS) can be attended online, providing you with a legitimate certificate afterward. 6. We’re Unhealthy: The truth is that the United States is not a healthy nation. Heart disease is still the number one killer of adults in the US and in many parts of the world, and things like smoking, poor eating habits, and lethargic lifestyles contribute to this pandemic. We don’t eat well, many of us don’t get enough exercise, and we practice poor stress management habits; all of which contribute to poor public health. We like to think we’re number one at a lot of things, but the sad fact is that we only fall at about 35 on the world scale when it comes to health and healthcare. 35th place is far from being a winner. 7. The Pandemic Has Shown Us Its Shortcomings: If there’s any sort of “silver lining” in the COVID-19 pandemic of 2020, it’s that the sudden onslaught of the disease has brought into sharp focus the glaring problems that exist in our current healthcare system. The bottom line? We don’t have the right infrastructure, enough dedicated people, or a good insurance system to care for our citizens. We need people who are compassionate and willing to put themselves at personal risk for others, and that’s rare enough nowadays.
