hi, i had a accident at work, tore the ligaments in my leg, and i have trouble moving, now on a walking stick, also i am awaiting surgery in september for a knee op, as my bone isnt aligned and its making movement aswell very hard, i am unable to do my job, and work dont want me in until after my op and all healed, but i cant stay off unless i get a sick note, but doctor wont do it as he says i am able to go on holiday (a week at my aunts) and i am able to sit down, but my job dont allow me to do it seating down, as i am a cleaner at a hotel, i have asked to be moved to another department, but at moment am unable to do this. please advice as so confused and now very stressed, as dont know what else to do. Thankyou
