Who is the instruction for?

Attention, please. Next week’s shifts have just been posted. With John on vacation this week and Margaret out sick, there are a couple of open shifts that need to be filled immediately. If you can work all or part of any of these shifts, please see me immediately. Otherwise, we will have to cover them as best as we can. I have placed a call to have temporary staffing ready if we need more staff members. Good luck today.
