Off topic, but this is basically unionization.
A class action uses a single lawyer paid by a percentage of winnings from the lawsuit or from everybody pooling their money together to represent a class of employees who are all in a similar situation and want better bargaining leverage with their employer.
A union uses a single lawyer on retainer paid for by a percentage taken out of employees’ wages to represent a class of employees who are all in a similar situation and want better bargaining leverage with their employer.
Just anecdotally, both my parents were in unions and I think they were better off than me in their work life because of it. I have a master’s in accounting and am not as well off as my parents, neither of whom have a masters and one of whom has only their high school diploma. Both are retired and set for life now. I have no such guarantees of my future and work as hard as either of them did.
It’s a very broad subject with a long history, a lot of room for corruption/mismanagement, a lot of real challenges that make it difficult for unions to hold the same sway today as they did in the mid 1900s (outside of a select few mostly that have political connections). And sometimes they make bad deals for themselves or for the companies they work with that hurt the workers in the long run. But I can’t look at my parents’ experience and say that the cons outweigh the pros for them.
