This has all the earmarks of a calculated plan on HP's part to get some number people to voluntarily quit without having to deal with layoffs or severance pay, and thereby reduce the amount of money they have to spend each month on employee's salaries, and accomplish it in a way that's not likely to leave them open to any constructive dismissal suit that they would have to pay out on. If too many people quit, well they can just hire more later... but they'll still be saving money because they'll have fewer salaries to pay out.
