If you're talking about Oracle, the large round previous to that they did had individual meetings with employee, manager, and HR. With so many layoffs it took a week+ to do, effectively torturing an entire set of employees who had no idea if they'd have a job by the end of the hour, let alone week.

I'm not sure there's any good way to lay off large amounts of staff (besides not getting yourself into the situation in the first place where you have to)
