i have often advocated for licensure and unionization in the information technology industry. employers don't like it, but they can't stop you from talking about it in the workplace. but basically people look at it as "i can get hired and get a job without a union" so nothing ever changes. that and not all unions are good. plenty of them just hand your dues over to the democrat party who they claim are advocating for pro-worker policies (but actually aren't) and you have union reps that embezzle money all the time.
