I will add to and emphasize what witness Bruske has said here.
One thing in particular that I've found in my own experience, too, is that in the evolving work landscape, especially since the COVID-19 pandemic, we do see people living in various areas and doing remote work. Trying to organize within the virtual setting is quite difficult, because people are becoming increasingly siloed. I think some of that siloing is happening through cultural and societal shifts in general, which is making workers feel much more disconnected.
Also, the hostility of retaliation and the consequences of retaliation only get higher in the face of a housing crisis, collapsing health care and lower resources within your communities. If you're looking at needing to cover leases, mortgages, children and whatever it might be, that fear of retaliation is really high, and the need for worker solidarity is n-fold beyond it. The more we are siloed and the more we worry about that, the harder it is to have those kitchen table conversations where people do feel supported and where they have the capacity to go ahead with a card check.
