Imagine you are a part time teacher who goes on your day off out somewhere unspecified (but definitely not a chemist or supermarket) and on two of these occasions you see a member of staff who is off ill in said place.
A large school but you know the other staff member reasonably well. She is known to suffer from various issues, including, it is assumed stress and/or eating related conditions.
What would your next step be , if anything?
Important disclaimer! I am neither of the staff members in this scenario!
