My boss never puts out a schedule on time. It's supposed to be done a week (or two?) in advance, but usually gets posted the day before a new work week starts. It's been this way for a year and we all just go with it.
This week, however, it wasn't posted until Sunday (the first day of our work week), and it wasn't even finished. Most of us were scheduled fewer days than usual, there were gaps where no one was scheduled at all, and some people were absent from the schedule entirely.
In my case, my boss forgot to put me on the schedule for today.
At some point this week, the schedule was amended… and no one was notified. I'm supposed to be at work in about 35 minutes according to the new schedule. But I'm not going. I expect I've got an hour before I get a call or a text asking why I'm not at work. Wish me luck.
Tl;dr: my boss posted an incomplete schedule and then changed it after the work week began. I'm not adhering to it.
