I'm one of the lucky ones who wasn't much affected by the menopause, however I have always struggled with overheating and sweat profusely in warm weather never mind how I suffer in a heatwave. It isn't life treatening I agree, but can be very debilitating and difficult to cope with, so I guess people with severe menopausal symptoms suffer similarly. When I am embarrassed about my condition I now say "I blame it on age and hormones" despite knowing I've suffered like it most of my life but I feel better being able to attribute it to something. In my youth I just said "I've always had a dodgy thermostat!" I've always had to struggle through it and take the rude remarks I occasionally suffer.
The trouble with having policies like this is that there will always be some who take advantage when they are not badly affected while others will work through whatever difficulties they face. Where will the line be drawn?
Working in a school I cannot be given a cool quiet place to work. If I open the windows in a classroom as I'm too hot there will always be at least one student who complains that they are then too cold despite the fact that they have chosen to remove their blazer/jumper, while I can't remove anything more without causing a major uproar!
Consequently I'm not sure how I feel about this. I don't know if people will require a doctor's note but if they do I guess it will depend how sympathetic their doctor is.
