I hate that I understood this

Do it slowly and don’t be consistent, sometimes I select the tile with 3 pixels of the thing its supposed to contain, sometimes I leave 2 or 3 tiles that clearly contain the thing, sometimes I just select a tile that doesn’t even match. Idk, it always works, I suppose the erratic behavior is what shows them I’m human or smth

Forgive my ignorance, but what is a union supposed to mean/represent in this context? What benefit may the employees get from unionizing? Has this actually ever worked before?
