In 2019, Facebook had 44k employees but by 2022 that number had more than doubled to 86k. Even with the current layoffs, they will only be back to 2021 levels.

It could be argued that it's reasonable to aim for pre-pandemic employee levels, given the drop in valuation, post-pandemic revenue decrease, and the significant loss in revenue from Apple's privacy changes.

This is just speculation and should be taken with a grain of salt. To achieve pre-pandemic employee levels, Facebook would need to cut an additional 20K employees.
