That’s how it should be - and is another excellent gesture of good will. But, based on a quick search, it looks like each of the 20 senior execs makes ~$2m/year (in cash, they get stocks too, but those don’t cost the company anything). If you halved their salaries, it would be ~$675/year for each of the 33k striking machinists - and does not totally bridge the gap to meet union requests. It also would omit SPEEA. But I agree, there are a bunch of levers they can and should be pulling.
It is actually easier to just get a different job with better leadership. You can say exactly what you wrote in your exit interview.
