and they got sued for that and lost. No union was involved in holding them accountable

Because there's no union who represents Google, Apple, etc. employees as a single cohesive block, there couldn't have been a union holding folks accountable. You're implying that the courts were successful, but only after Googlers had an employee revolt (read: a non-union-organized strike!) against being taken to forced arbitration.

Yeah, they got a small slap on the wrist for that one. My point is the presence of snacks and perks does not preclude the exploitation of labor.
