Absolutely. For example, Google will reimburse you up to $12k a year for courses you take that are related to your job, and even offers up to $1,200 for everything else. So if you want to take, say, a cooking class, they'll even help out with that a bit.

Almost all, I'd never heard of a tech company not do it.

My company doesn't and a whole slew of ones I've talked to don't either... I'm not sure what bubble you are living in where you've "never heard of a tech company not do it'.

Microsoft has this program but it's pretty bad. Only masters courses are allowed with managers approval. Rest is out of pocket. Most managers don't approve. Tuition benefit is very much a myth.

Microsoft tuition assistance is available for both undergraduate and graduate programs. There are annual limits to how much is reimbursed and you get more for graduate school. Yes, it does require manager approval too. (I work at Microsoft)

The parent said "companies" not necessarily "tech companies".

Really? I know a bunch. Almost all startups, for starters.

As in university tuition? Or as in sometimes they decide to send you on a course and pay for it?

Facebook doesn't do it either at least from the last I heard, because supposedly they don't care whether you have a degree or not.

Yes, although the IRS only allows companies to offer ~5k/yr before the money becomes taxable compensation.

Travelocity paid for 100% of my tuition and books to finish my Master's degree. I did sign an agreement that I would stay there for two years after graduation, though, and I had to maintain a B or better average.

It's pretty common at manufacturing and (non-software) engineering companies.
