Hi, I was told off by my head teacher today because I took a day off back in September for tonsillitis and two days off last week for tonsillitis (again), I couldn't swallow or even talk at times. She said it was a concern I had taken 'so much time off' - 3 days to be exact. She also said that tonsillitis is not a 'good enough reason to be off' and I should have come in. I looked at my job contract and it clearly states that I am entitled to 25 sick days each rolling year - she said that I am only allowed 3 periods of absence, and I have already taken two of them in this first term. She also says that I could have a disciplinary action something something set against me if I take a third period of absence this year. What should I do? Advice please.
