Whether you love your job or not, I'm sure most of us have had the thought of walking out on our jobs at least once. But, we have commitments and debt holding us down, so we choose to just power through, no matter how unhappy we are. 

However, there are some times where it just isn't right for you to keep at it anymore. Here are 6 signs to tell you when you just HAVE TO resign:

1. Toxic Working Environment

If your work environment is leaving you mentally exhausted every day, then that's a huge red flag. Whether it's corporate politics or irrational requests from your superiors, these things only add on to your already stressful work experience. This will result in mental illnesses in the long term and that is never worth any amount of money they're paying you. If speaking to HR doesn't improve the situation, time to leave.

2. No Sense of Purpose In Your Work

In a LinkedIn research among 3000 applicants, 35% of professionals dislike their current job because they cannot find a sense of purpose in it. This is important to many as it gives a sense of fulfillment. Ask yourself, are you proud of your work? Are you making a difference in someone else's life? Is your job meaningful to you? If all these above answers are no, then you'd probably want to reconsider your job.

3. No Space for Improvement

We're not referring to just salaries and job positions (although that is equally important), we're referring to skillsets too. If your job allows you to take up new roles and responsibilities (even without a change in position), then that is a good opportunity to learn and improve. However, if you think your job is mundane and repetitive, then think about moving on, even if the salary is increased year over year.

4. Superiors Promising Empty Dreams

This is especially true if the company you're in is smaller or is a startup. It's good to have dreams, but your superiors should back it up with actionable and reasonable plans. If they keep promising you good future compensation but deliver nothing after a while, then that's your cue to leave.

5. Salary Mismatch

Salaries are one of, if not the main reason people use to select their jobs. A salary mismatch will definitely also be the main reason you should leave yours. You can start by comparing with the median salary of other people in your position within your industry. If you think your salary does not justify the amount of work you're doing, talk to your superiors. If you can't come to an agreement, then that may be a reason to move on.

6. Your Job Is Not On Your Ideal Path

If you're even thinking about changing industries, then start looking at the long game. Take time to sit down and write down your end goals. See if you can connect your current job and industry to your end goal. If you plan to do something with investments, does your current industry link to that? If you plan to migrate to another country, does your current company have an office over there? When you can't connect the dots, then perhaps you should make a move.

If more than one of these signals pop up in your current job on a regular basis, then do reconsider your career choice. It's ok to make a mistake, but the biggest mistake is staying in it.
