For anyone in Toronto looking to supplement your income and/or experience, the Toronto Public Library is looking for library staff to cover Sunday shifts from September to January. See: Toronto Public Library Employment Opportunities. Shifts are every Sunday or every second Sunday, 1:30 - 5:00 p.m. for librarians, senior library assistants, and public service assistants.
I tell you, if I wasn't doing so many things already, I would consider it. This would be a great way to add a few new skills, especially with regard to dealing with the public. Plus meet library staff from other industries. It looks like possibly the teams go to different locations, also.
