I had a colleague who has diabetes, he regularly injected in the workroom where we all had lunch, privacy wasn't an issue. What's wrong with the toilets anyway? I don't ask for a private room if I need to take medication because of a cold, to me, injecting insulin is just that, medication! If he needs special hours, then presumably his condition is too serious for him to be able to cover the job spec and he needs to rethink his choice of working as a teacher. He is being completely unreasonable and I'd get Occupational Health involved straight away. It is ridiculous to try and keep things "in house" when the demands are being so unreasonable - to me it's like if you didn't want to involve a union as soon as your professional judgement was called into question, for instance. That's what they are paid for, get them involved, no shame involved. They're the professionals here. What next, giving kids with diabetes an extra long lunch break? Please! You may find the following document useful: http://www.diabetes-support.org.uk/Disability%20discrimination%20in%20the%20workplace.pdf You'll see that it disagrees with some of what I've said, but actually it doesn't mention that the work room should be close to the work place, and it doesn't mention longer lunch breaks, just more frequent breaks.
