working in appointments

Al
Anyone else have problems with trying to get in these appointments? Now that they are biweekly, it is stressing me out. Basically I have to take what my doctor has to offer because he has a ton of patients! so I have to work around my school schedule, daughter's school schedule and my work schedule! My manager was miffed with me (it's retail) that I had to find someone to work a shift because my doctor's appointment interferes with it. Well, if you would post the schedule earlier, I could work around it! Rant over lol
