You want to leave the company and expect them to make it easy for you with benefits payouts? Wake up and grow up.
No, you don't get a bonus if WFRd in any quarter. Why would any manager give someone leaving a bonus?
No, you don't get paid unused vacation unless it is state law, such as Cal. Idaho certainly doesn't, as I know people laid off there, so the person commenting on that is wrong. And for people whining about what a big loss this is it, you are full of crap: First of all, you accrue it throughout the year, so leaving in April means nothing. What have you earned... four days? Second, if you get to December and still haven't taken a day off, that's on you. You aren't that important and the work will be there when you return.
Complaining about OT as an exempt salaried employee? No such thing as OT.
Any company owns your patent that you produced as an employee, so not sure why anyone would expect some payout from that after being terminated.
If people don't like it, then they need to start voting Democrat and joining unions. HPE isn't doing anything wrong or unethical. Apple, Google, and everyone else does the same thing.
