Tech workers are often part of unions over here (Belgium), the same as anyone else. Let me tell you that unions do not make for a panacea.

Among my working (not necessarily tech) peers, anti-union sentiment has been increasing. Likely because they've been inconvenienced by recent union actions (mostly public transport strikes). Individualism is a hell of a drug.

Being a freelancer, most unions see me as a traitor or a thief. So I have some mixed feelings about their current incarnations.
