Well, outside of some extreme cases (such as professional sports), I think you see this in a "company town", where laborers could theoretically move, but usually lack the means to do so. (And increasingly can't afford the higher cost of living of the places where the jobs are.) Anyway, when the "company town" economies were thriving, they usually coexisted with unions, to help balance the ability to negotiate wages. ...The fact that we're seeing labor's share decline within cities (where there are clearly many employers) dispels me of the concept that monopolies/oligopolies are responsible for this decline.
