Beware of assuming that every law passed with the intent of protecting workers actually has that effect. Yes, some laws really do protect workers (e.g. banning noncompete employment clauses). But laws that make it very difficult to get rid of employees (either because they're not doing a good job or just because you can't afford them anymore) act as strong deterrents to hiring, and that tilts the power balance strongly in favour of employers over workers - which is exactly what causes so many problems in the first place.
