Employer Lock In
Many employees would like to JustLeave their existing jobs, but there are many things that can keep people from leaving bad jobs:
Restrictions
Golden Handcuffs
The above make some people feel that they are "stuck" with a particular employer, no matter how bad the job is. In the case of the "restrictions", this feeling may be valid, but people who keep themselves locked in GoldenHandcuffs have only themselves to blame.
