Not only that, for it to even happen you'd need one of two things:
1) You have a very specific skillset which has such a high market value that you're not willing to change roles, but is esoteric enough that there are no other local employers for that skillset even though there are plenty of local employers in general. This is obviously not the common case, and is generally not a huge problem, because the "victim" is someone who can still command high wages and extract concessions from the monopolist because they still have the ability to switch roles and get a job doing something else for someone else.
2) There are not plenty of local employers in general. This is the aforementioned problem case where the incumbents capture the government and use it to inhibit competition, which must be prevented.
