In the USA at least, there is a much higher transaction cost for an employer than for the employee. If an employer makes a bad hire it will be costly for them to fire them, and the work they got hired to do will not get done. For an employee there is the opportunity cost of working in a bad situation vs a good one, but getting out of the situation is far less costly. In fact, you may be marginally more valuable because you have a few new experiences on your CV.
