What bonus??? - Anonymous employee Edustaff Employee Review

Edustaffs response about low pay talks about bonuses. It gave me the impression that they made the pay higher across the board. So out of curiosity I called them to find out what this meant. The person who answered the phone wasn't quite sure. But she thinks that it's for subs who sub for so many days will get a "bonus". But did not elaborate what it is. First of all, who gets the opportunity to sub so many times??? That's only driven by need. Subs have no control of this. So in other words, a sub has to attain a level to get a bonus. But isn't this already the case?
