Hi, im a security guard. my job requires me to work 3 different shift patterns. Some days im tired all the time, others i feel fine but often quick changes can make me feel dizzy and often i get forgetful. I walk a lot in my job which is good regular exersize but as in the case of yesterday i was phisically tired and started an argument with a collegue which is totaly out of character. i tested my blood suger level and it showed i was low. From time to time i have to sit down to either take a drink or eat which is fround upon by my collegues. we do have set periods in our shifts where we are sitting for two hours but i still need to sit from time to time when patroling. My diabetes type 2 is reasonably controlled at the moment with tablets. I also have an underactive thyroid which also creats problems for me together with the diabetes makes the working day a bit of a rollercoaster ride. My employeres are aware of my diabetes but not the problems i face day to day. im worried that if i tell them i will lose my job. I dont think they will put me on a fixed shift pattern to suit me and there isnt an alternative possition i could go to. what advice can you give. thank you
