Ford C-suite took home $71 million in 2021 (most recent year I could find data). They could give each worker a $1000+ bonus and still walk away with $10 million. Not that $1000 is enough for each worker, but just to illustrate that there is a ton of money floating around, they just don't want the workers to have it. It's not future investment they're worried about (they get massive tax breaks for all these new facilities, and new car designs are all being done by salaried white collar engineers anyway), it's shareholder profits. Ford doesn't want to lower their reported annual profits by increasing their worker costs.
Fuck shareholders, and fuck the C-suite for looking out for their interests instead of their workers. They don't actually produce anything. The workers are the real company asset here, not some Wall Street goon who bought stock.
Why should they not? They posted an inquiry, looking for advice. That is their reason for posting.
They do not owe personal information beyond what is required to answer the question. And typically, with regards to anything resembling a legal matter, the less information posted publicly, the better.
