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?
No, it still is. Most of the people I work with are boomers that tried to kill unions or upper middle class genx or millennials that think they pulled themselves up by their bootstraps. The tech bros have definitely not gone away.
