Because they didn't. According to layoffs.fyi Ebay laid off 200-500 people last year as well.
But even if Ebay did go on a hiring kick, is it true that all of those employees had to be laid off? None of them could be retrained?
Why is it that so many companies seems to regularly make the *same* mistake of over-hiring and then "needing" to downsize?
And if Ebay did a layoff last year why not lay off these people a year ago? Did they miscalculate last year? Was this layoff planned more than a year out? What changed in a year that makes Ebays calculations more accurate now?
