This is anecdata but two high profile tech layoffs you've read about on here in the last few years gave out more like 2 months per year served, on the low end.
This is an outlier, and while commendable (I’d love to hear who it was, positive signal about who to work for wrt to respect and treatment of workers), it isn’t industry standard by any means. Great if you can get it, but don’t expect it.
Off-topic but ESL person here, why "anecdata" and not "anecdotal"?
It’s anecdotal + data
For the benefit of ESL, it is a portmanteau of anecdotal and data.
