      Pros

      The systems for subbing through S4T are centralized and streamlined, this makes working with them really great. They have a central database of openings and are great about getting teachers placed!

      Cons

      They call you relentlessly unless you manually, continuously enter your availability on the online database. I've tried sending e-mails to clear up the days I'm not available so I don't get calls, but have never gotten it handled.

      Pros

      Somewhat easy application and easy hiring. Can choose days to work and assignments available everyday. Good to get experience in schools if no education degree yet or deciding.

      Cons

      Same day or very short notice of assignments available (depending on location). Constantly checking app for work. Minimum wage for this important job.
