Hey
@janeliz Firstly well done on getting the job
Your employer has to offer you reasonable adjustments to do your work, which should include breaks to test, however it is essential to keep your BG meter and hypo kit with you at all times so you need to speak to your companies HR dept to find out what allowances can be made to ensure you have access to your kit at all times and that breaks are available to you. It would be good to get a plan in place so that you feel comfortable to perform the work required without it affecting your diabetes management. Discrimination only happens because an employer doesn't understand what type 1 is about so developing a plan with them will allow you confidence that you can get on with the job in hand.
This is a useful pack to read through on diabetes and the workplace to understand your rights:
