The same thing happened here in Alberta, the brief interlude of a centrist government a few years back, made it so farm hands had to be covered by basic safety codes all other workers are allowed and they freaked out and threw a hissy fit. They even got an exemption so their family farm hands would remain exempt from basic safety protections.

Oh and the starting inspecting the housing offered for the farm hands and told them no you cannot shove 16 workers into a tiny work shed, with threats of deporting then if they talk.
