" It’s increasingly clear, for example, that monopsony power is depressing wages; but that’s not all it does. Concentration of hiring among a few firms, plus things like noncompete clauses and tacit collusion that reinforce their market power, don’t just reduce your wage if you’re hired. They also reduce or eliminate your options if you’re mistreated: quit because you have an abusive boss or have problems with company policy, and you may have real trouble getting a new job. "
