I have been employed as a TA for a long time. I have had various roles, but nothing perminant. I am constanly asked to cover people on maternity leave, but when a vacancy comes up for a more perminany position, I dont even get an interview! During my time there, I was offered another job at another school and the head said they didnt want to lose me, so I stayed. I have recently asked to do my HLTA status, said I would pay. The head told me as I only had a 12 month contract, it would not be worth them letting me have the three days off for training!
