People with little financial means often don’t get a fair shake from the legal system.
In labour relations, it is not much different. So it’s one of the main reasons workers unionize.
Individual workers don’t stand much of a chance against unfair treatment or an employer who is determined to get rid of them. The government is not much help either in that employment laws are rarely well-enforced without independent legal representation. If you want to argue your case, you need to hire your own lawyer—something most people can’t afford to do. Besides, the employment laws aren’t designed to get you back to work, but to negotiate the price of your departure.
