Complete and utter shambles.
Home tutors employed by local authorities never have the security of knowing if and when they will be employed.
Dealing with problem children (and their families) supplying not only expertise but also in many cases books, paper, writing implements, travel costs, all with minimal backup. Not to mention the time spent filling in forms which get filed and never again see the light of day. Reports, assessments, lesson plans for day, week, term. Risk assessments.
Casual labour? Labour, not casual.
