You are not given shifts as a tutor.  We send out tuition assignments to tutors as they become available - this will include details of the time and day of the tuition, the pay rate and how long the assignment will run for.  Tutors can apply for as many tuition assignments as they wish, but we expect tutors to have checked that they can commit to the entire run of an assignment before applying. 

The amount of available work varies depending on the time of year and the demand from schools and we cannot guarantee that work at a particular time/in a particular area will be available.
