No, this has never been the case. Companies are and always have been very conscious of wage and salary expenses, as it's one of the most controllable categories on the P&L.
But like if your company is making money hand over foot you didn't typically cut staff by 25%. You could just as easily do a hiring freeze and get out ahead of it. I mean if your profit metric is showing all green and growing you have to be really cold to say we need to fire 1/4 people now why? (to maximize shareholders short term value of course)
And one of, if not the most, expensive costs
They are making $600k in net income per employee. 10+ years ago, I'd never seen a mass layoff at any company making that kind of money per employee.
Their net income is up more than 2x in just the last 5 years. 10 years ago, Microsoft only had $85B in revenue, now they are up to $134B in net income, and they need to let 25% of the company leave?
