It used to be that if you retired on the 1st or later day of a quarter you would get paid for any unused vacation days. Not so anymore. As of July 1st this is the new policy
CURRENT EMPLOYEES — COMPANY PROVIDED VACATION ENTITLEMENT
Employees earn their annual Company provided vacation based on the number of calendar days within the year. For example: If an employee’s maximum annual accrual (see Section E.) is 20 days, their daily accrual would be .055 per calendar day (20/365).
Less what you have already used, you'll get paid for.
For me it is almost 8 days I will not get paid for now. Which is about $3800 I was planning on. One more way to sc--w the employee.
BTW - I do not see the ability to take even half the lump sum that is being offered this year as an option next year. So plan accordingly. Don't say you weren't warned
