You have to REALLY drag yourself to work every. single. day.
You dread going to work because 1. You have a toxic job; 2. You don’t want to see your boss; 3. You haven’t completed your projects yet; and 4. There is no motivation for anything at all. AT ALL.
You hate what you do.
It's not rocket science. If you don't like what you do, you won't really perform well. If you're making your boss look bad, and you're constantly asking your teammates to cover for you most of the time, it may be high time to look around for new opportunities.
Your job is making you physically sick.
If your work is causing you to be sick—physically or mentally—then it’s time to go. Hypertension, insomnia, fatigue, anxiety, irritability— and yes, even depression are some of the side effects of too much stress.
You hate your boss, and the feeling is probably mutual.
According to Time Magazine, “The majority of people quit bosses, they don’t quit jobs.” It’s one thing to have conflicts on a professional level, but it’s different if your problems with your boss have become personal. If you've tried to resolve this conflict more than once and your relationship with him didn’t improve, then it’s time to leave.
You can’t get along with your colleagues.
You just don’t fit in—no matter how hard you try. Whether you ostracize yourself from your colleagues, or you just feel like your officemates deliberately leave you out, maybe it's time to find a new company where your skills will be appreciated.
