I have a problem and I wonder if anyone is in the same position? I am a school teacher who has asthma. Unfortunately sometimes my asthma gets so bad I find it difficult going into school and especially trying to teach children. This has meant that I have had to take more than an average amount of days off school. As a result of this I am given grief by my head and I feel really guilty letting the children down. I am constantly reminded too that I am costing the school money as they have to find a supply teacher. Is there anybody else who has this problem? Is there anything I can do? Please help.
