Using Up Paid Leave

I finally used my last half-day of paid leave out of the 5 days I had to use by the end of September. Next, I have to use 3 days of summer vacation by the end of October. I plan to use 2 days for medical appointments. I was hoping to take the remaining day on a Monday for a three-day weekend, but I can't get the day off anymore 😭 I guess I'll have to use it on a different day... It's tough figuring out when to use paid leave...
