A prime example of why "unionization" is good: You only need two people to do this differently and be told the opposite by the administrator (preferably the same one but not necessarily) and you've proved that it's BS.

That's all theory of course and in practice I bet people did talk about this afterwards and figured out it's BS and it didn't help either way. But it's easy to "find out" (and then try to do something about it) if you stick together. But if nobody sticks together on it and tries to do better for themselves by themselves, everyone does worse for themselves in the end.
