The government is the only entity tracking union density for the US as a whole. When we talk about union density it’s a government-tracked statistic of how many people are in unions. If you were referring to another source of such statistics with which I’m not familiar despite me organizing in space for years and following it closely, feel free to share it.

I’m sure union density has increased in certain locations but overall it has decreased.

The state of organized labor in the US is not actually looking good there are just some salient examples getting headlines. Those examples are atually pretty iffy if you familiarize yourself with them.I would never use US organized labor to give people an example of current wins. That’s setting them up for disappointment and maybe even nihilism when the realities make themselves more obvious later.

For example, it is plausible that SBWU may never get a contract and will lose via slow attrition. Amazon warehouses are in a terrible state. It’s really all up in the air and we should not expect big wins, particularly from SEIU’s half-assery and ALU functioning mostly as a Chris Smalls fan club.
