OH nay nay, those days are already earned and they have to pay them, Federal Law...
Sorrytogo, any vacation time is still owed to you for the current year, option days are not. If you don't get an answer from UPS soon, contact the National Labor Relations Board.
There is a good chance the check has been issued and is setting in the Center Managers office. When I retired my vaca pay was in the office for about 6 weeks, no one bothered to notify me they were there. I had to go through the union to even find out where they were.
