I'm really interested in what they are:
- fear of a new beginning
- you can't find a new job
- you had a job offer that means much worse working conditions
- you still feel the situation here is bearable
- you suspect that the grass is much greener somewhere else
- waiting to be cut
- another reason?
I have changed several companies so far. The more jobs you change, somehow it seems easier to decide to leave and find a new place for yourself.
