I am a teacher currently working 2 days a week. I have been working 2 days for the past 5 years, following maternity leave. Prior to that I worked full time at the same school for 5 years. Today my headteacher told me that due to staff changes she wants me to work 3 days a week from September. I really don't want to increase my hours. Can anyone tell me if she can make me do this? I have emailed my union but in the meantime i am awake worrying!
