Getting that critical mass is the big hurdle as I see it. People are afraid to show outward support for mass action if the perceived mass is only you and Bill from accounting. There's the risk that if you start making noise, regardless of whatever laws might protect organizing, the company tosses you for 'other reasons'.

I worked in a place for about 6.5 years that towards the end started hemorrhaging workers to the tune of about 1/3 the staff over a summer. Having grown up in a union household I gave some smoke break talks about how we could start one. Eventually without traction there I put together a local area study of similar work and brought that in to the VP in charge and after it went up their chain everyone in the place got around a 15-20% raise. Then about 6 months later I was dismissed for 'poor performance' after 6 years in the same role. 🤔
