I know an ex-colleague who worked as a teacher, a good one, then suddenly left to work in a private school, smaller classes, less stressful. She had a bike accident, so gave up entirely. Encountered some years later, she was working in Tesco, put my overall on, work the hours, hang my overall up, go home, nothing more to do with work, less stressful.
Next heard of, working as a Doctor's receptionist.
Last heard of, working in the Doctor's surgery away from the front desk, too stressful, patients were rude to her.
The problem:not the jobs, the person.
Sad, a waste of ability.
