Agreed, and not sure why you're being downvoted for this.
- They must use the court system, and do so probably without legal representation unless they can find a lawyer willing to work pro-bono. This requires time and money
- At the same time they’re almost certainly job hunting because while retaliation is (sometimes) illegal, it’s trivially easy for businesses to cite other bullshit reasons for firing people and be entirely in the clear, because that’s even harder to prove in court than wage theft
- If they do manage both of those, they now have a documented history of fighting for their rights as workers, and bosses do not like that. It makes them inherently riskier to hire.
