I recently started working as a supply TA for an agency. I have had a long term placement with the same school since I started in May, but school germs are killing me! Was off for a week last term with horrible cough/sinus. Been back a week and a half and have got the same thing again despite first defence nasal spray. I feel terrible as the school is so short staffed. I love the work, but I am on my 3rd illness since I started. It's not just mild sniffles, either. I have had more sickness in the last 4 months than I have had in the last 10 years. Has anyone got any tips for surviving the germs in a school environment?
