When one leaves a Boss from Hell it is important to get another job which is unlike the first. It could be part time, it could be in a different field, it could be more self employment.
To return to work and regain the person you were before the Boss from Hell is vital.
To be aware of the traits you adopted; the unworking, the clock watching, the dishonesty, as well as the prisoner mentality can only be done by being exposed to other venues.
One has to be alert, regardless of the economic benefits, not to go back to work for similar boss.
It is vital that one has a period, equal to that one was employed by the Abuser, to regain ones self. This period of time is key.
If you worked for a Boss From Hell for two years, you need two years to regain yourself. Be conscious of this ‘healing’ time.
