So tomorrow someone ie coming to take a look at our water meter and we need to be home.

My sister was originally going to come over and let the guy in. BUT she has a final, my wife cant take off and no one else can come.

I havent been at this job long (july), but i have 3 days PTO saved

I took a day off for a funeral last month and im afraid to ask my boss (anxiety)  I only have 3 work days this week and feel bad taking off before a holiday 

What should I do? Should i talk to my boss and take a PTO day?
