On that note, I think Amazon's tuition reimbursement is also more meager than that of Microsoft's, if not absent altogether. MS is happy to cover something close to 10k a year for your graduate degree.
That's comparing very differently compensated employees, though. This Amazon program is for hourly employees, such as warehouse staff. My guess is that Microsoft's willingness to pay $10k/yr for graduate tuition only extends to their salaried white-collar employees, unless they treat their hourly staff a lot better than I'd realized.
