What happens when you don't pay fair wages

Employess of PHS, a company that provides healthcare services to prisons, are on strike. They're protesting what they call unfair labor practices and the failure to sign a new contract. I usually don't write about the private healthcare providers, which are their own mess, but I just wanted to link to this because the private medical providers, just like the private prison operators, often pay considerably less to their employees than a state would. This is one of the main ways they keep costs down, because salaries make up a large portion of a prison's operating cost.
