There are certainly situations where if you say "not it" the work just falls to other people (or worse, a single person) who is less comfortable or able to say no.

But there are also situations where a person has been said 'yes' to so many times that they just assume something is wrong with anyone who tells them 'no'. Enough people have to say 'no' that it becomes normalized. Either a more 'fair' process is made or they finally hire enough people to do the job right (haha, who am I kidding, they'll never do that, but you can at least get to 'less wrong').

It's really a tough matter of reading the room. Sometimes if you see someone asking for something that doesn't necessarily interest you, asking for it too makes it okay. Other times it causes the boss to catastrophize (well now everyone will want to do this so I'm not going to let anyone do it) and shut down.

Asking people to follow labor laws that are almost 100 years old is not that big of an ask. I know everyone is busy LARPing feudal England half the time but someone has to call bullshit, and it's mostly the people with just a little bit of power who can actually do anything about it.
