I think where a lot of companies find themselves is "[last year] we think we're going to grow 20% next year and need to hire 15% to cover that business growth; [this year] oops, we only grew 5%, meaning we should have only grown headcount by 2% and now need to layoff around 10% of our staff to keep our financials sound and protect the jobs of the other 90%"

I think that's a lot of repeated applications of the former case.
