This is a really great thread idea. It can feel a bit awkward at times having diabetes in some situations.
I think having open communication with colleagues and your employer is really important. Telling them directly what it is you need from them and how they can make life a bit easier for you, as is their duty of care.
I was quite shocked when I began my job to find a risk assessment while I was cleaning up that said I was "not to take medication on shift due to the medication being unsafe to service users" shock horror! So even though most people in management positions should have an understanding of their role in health and safety, clearly not all do.
As for making things easier- I work 24-32 hour shifts so tend to have ana abundance of strips, insulin, glucose tabs at work just incase bgs go a bit awry.
