Record profits cannot materialize trained labor out of the aether. They can offer more money - and the new contract does offer a pay increase of nearly 25%.
Record profits can do a lot to start ginning up that trained labor if you're willing to use it, though, yeah? Can do a lot more than just offer more money -- you could, ferex, run slimmer margins so you're not working your labor force so damn hard, heh.
... anyway putting some numbers on it, the 67k you mentioned, on a 335 day working year, comes out to like 16 USD an hour if they're seeing 12 hour shifts (i.e. it's barely more than bloody minimum wage in some states). That is shit when you're talking the hours and labor involved, minimal requirements or not.
It gets better if you're looking at a more reasonable calendar (the 250 day year proposed upthread would be 22-ish, which is still pretty goddamn abusive for 80 hour workweeks, but not as bad), but it doesn't approach actually attractive unless the hours involved are made reasonable (and one of the things causing this fight is that they're not, and the companies involved do not appear to be interested in making them so). A pay raise from shit to less shit is still shit, et al. People work those kinds of hours for less, but it's not something they do by choice, y'know?
100k+ (call it 120k, just for a ballpark) would be closer to 30-40/hr on 12 hr days (depending on the calendar involved), which is approaching at least less
unreasonable for a schedule that could be including 80+ hour workweeks, but like... still. If that's what they're offering to get worked like a dog it's zero bloody surprise they're having staffing trouble. They have trouble managing that with nursing, and they see average wages even higher (the attempts to actually attract nurses, i.e. travel nurse wages, average around 50 USD/hr, stateside -- it's still not enough to manage to fully staff due to the labor conditions involved, of course).
... or in other words, it sounds a lot like that proposed pay raise is a joke, and a bad one considering what's being asked of the workers involved. They don't need a 25% pay raise increase if they're going to try to attract folks to 80 hour workweeks, they need to add another 0 somewhere after the 2 in that percentage.
