I’ve been a software engineer for around 8 years and have had 5 different employers. One (Allstate) allowed us to buy more than the 15 vacation days, and gave us a few sick days I believe. They upped you to 20 after the first year, which is somewhat common in my experience. But no other job I’ve had, including 2 startups, gave sick days.
Microsoft, motherfucking Microsoft, starts you off at 15 days of PTO per year. I’m not really sure why people are itching to work there.
