Shit, I mean they only have like 3 departments that actually need staff with their manufacturing pretty much entirely automated. Purchasing, sales, and r&d. Purchasing is likely a stressful job there and probably paid worse than the others. Sales is dwindling as they move more of their sales to long term b2b contracts. They probably have less people on that team than they used to, and those people are likely in charge of very large accounts. Then they have a very large very well paid r&d department.
All of this makes me wonder how many employees they even have. It can't be that many when compared to more traditional manufacturing industries.
