Looking for another job when there are massive cuts like this also degrades the salary they accept on their next job because of the competition.
I wish companies, if possible, throttled layoffs a bit more instead of large chunks like this, but that is unlikely as the board/CEOs are looking for a stock uptick when they do and don't want to drag it out to affect the market value (translation: their own pay / stock value/price).
We rarely look at the amount of money lost in communities when things like this happen but it would be nice if reporters put out the lost community dollars/salaries along with the layoff number. The Great Wage Stagnation continues in our consumer driven economy.
