> Layoffs are a very normal thing for businesses to do.
Didn't used to be, except in extreme circumstances. Was seen as a really bad sign.
To the extent there's "science" on this, it's a lot less clear than you might think that a policy of reaching eagerly for the layoff-button is long-term beneficial to companies, i.e. there's a good chance it's a cultural fad, you do it because "that's what's expected" and perhaps investors get skittish if you don't, for the circular reason that... that's what's expected.
People generally complain about the interview process being bloated while also not giving a good signal - is it then not better to hire people for a while, see if they perform and then letting them go again? Though perhaps in Meta's case they hire a lot while also having cumbersome interviews, I don't know. I just feel like there are perhaps some benefit in being quick to hire and fire.
What people dislike is the boom-bust cycle inherent to all levels of a market economy. During some years, these companies suck people up like a vacuum -- that can be bad if you're on the inside and all of a sudden the culture goes out the window, or if you're expected to onboard 3-4 people at the same time, or you end up with a reorg every quarter. Then, on the other end of the spectrum, companies shut down (non-backfill) hiring entirely and layoff huge percentages of the company, with no guarantee that you'll be safe just because you're doing a good job.
Human lives do not work like this. If you're getting married, if you have an unexpected hospital expense, if you want to buy a house -- these are not things that "market cycles" will plan around, but you have to.
Being quick to hire or fire is not the problem. Massive overhiring and massive layoffs are.
