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?
The NLRB recently ruled that Google is a joint employer of Cognizant employees contracted to Google, because Google sufficiently controls the working conditions of those employees. Google is attempting to ignore the ruling, which is illegal but slow to have consequences for them.
NLRB is going to have to convince a court (probably several) that their stance is the correct one before that ruling becomes at all real, though.
