Always so much confusion on the weekend holidays.
Veterans Day is Saturday November 11th, 2023
Post office is CLOSED on Saturday, November 11th (exception may be RCA/ARC Amazon delivery)
If your regular day off is Saturday, you should get Friday, Saturday and Sunday off. If you are made to work Friday, then you will get holiday pay plus normal workday pay, or you may choose DACA code G to receive a day of annual leave instead of holiday pay. More about DACA code G at this link.
If your regular day off is Monday, you should get Saturday, Sunday and Monday off.
