no you dont, in Europe there is a lot of legal aid and support available to bring these to employment tribunals. you dont have to be rich to get justice over here (but as with everywhere it does help).
well free legal aid is worth what you pay for it in mine and other's experience. hopefully you won't have to rely on it someday. being rich certainly does help.
Not at all, in Europe this kind of justice is accessible to most people (and most likely you will win the costs as well). OK, I am speaking for Spain but I guess it is the same thing in all of the EU.
