Relationships with management often result in surprising “changes” when you try to unionize. Companies are top-down dictatorships. Except in extremely rare circumstances, the reaction will come from the top and filter down through management, who will need to choose between losing their job and engaging in union-busting: sharing information (perhaps naively) with their own “superiors”, stalling, helping build anti-agitprop, and eventually firing organizers. Smart companies will try to leverage personal relationships to undermine the campaign, “sure they fired KatySosa, but the guy who announced it is such a nice person and they said it was for performance reasons. That guy has us over for parties and I’ve met his kids! He wouldn’t do anything for a mean reason.”

You should go into any unionization campaign expecting to be fired and for your coworkers to need to strike / do walkouts for your resinstatement. Are your coworkers ready to do that? I don’t mean to discourage, the advice I’m giving is meant to increase your chance at success. You want to build up with structure tests and a committee before showing your hand or the compsny will just fire you and kill the campaign early through this intimidation.

I haven’t checked but if you’re the person who got active in part with PSL support I think it should be noted that they are not a known quantity in labor organizing. They might be more interested in radicalization than a successful campaign, e.g. suggesting agitprop before building a committee or a list (list building is always step 1! Always!). Or PSL mighy just be naive.
