The headline numbers:
They're cutting 40% (edit: the post actually says "nearly half") of the workforce (4k out of 10k). That's huge.
The severance is 20 weeks of pay + 1 week per year of tenure, stock vesting through May, 6 months of healthcare, their corporate devices, and $5k cash.
They're going from over 10k employees to just under 6k. So more than 40%.
That significantly more generous than the 12-16 week severance packages being doled out by big tech during the great layoffs of 2022-2023 if I remember correctly.
