5. If possible, change your schedule or seek out other positions.
Before leaving completely, look into taking baby steps toward the front door. If you have problems with catty coworkers, see if it’s possible to change your schedule so that you can work with people you can at least tolerate. If you have some seniority, look into other opportunities within the company that you qualify for and that will better accommodate your lifestyle. You may be stuck at the same job, but that doesn’t mean that there’s no flexibility available. Don’t be afraid to express your grievances, as long as you can do so professionally. Unless you work for a tyrant, the worst you’ll probably hear is, “No.”
