In short, LibStaffer is a calendar and scheduling tool. Each part-time employee will have an account to see daily, weekly, and monthly schedules, sign in and out for shifts worked, communicate using the "wall" feature, and swap or pick up additional shifts.
Your supervisor will post updates and other relevant information on the LibStaffer Wall, so please login regularly. As with all work-related (and most college-related) information, your login will be connected to your SUNY Broome email account. You should also be checking this email regularly, or configuring it to forward to another account that you use.
