At my work just all me and my fellow techs in a meeting we basically expressed shared frustration at wages not increasing at all in last couple years despite the company making billions.
It appears we were all individually expressing this and it boiled over cause nothing was being done.
So are there any organizations collecting signatures or potential members with the goal of forming one later?
You are correct but many workers in the US (tech and otherwise) are only aware of unions as historical tools of organized crime/corruption, or are libertarian (which gets higher representation in tech circles) and believe the free market will provide for them and/or that unions excessively harm companies. There are likely other reasons but these are what I’ve heard from people I know.
These views are reinforced by corporate and libertarian (which is of course funded by corporate) propaganda.
