ive worked as a hotel receptionist for the last 9 years, im currently 16 weeks pregnant with my 3rd baby and im still suffereing with hyperemisis gravidarium which ive had since week 5 of my pregnancy, to cut a long story short i just cant work anymore,i had it with my 1st pregnancy and it didnt go away till i was 8 months with him, im being sick several times a day all day and night and im just phycially drained and i dnt see it ending any time soon, im constantly having to take time off unpaid due to hospital/doctors appoinments and the doctor has advised me to go on sick until my maternity leave starts, ive brought my MAT leave date foward to the earlist i can leave and added all my holidays onto that before the date so i can leave work on the 15th september, but the only thing stopping me is my dad is getting married at the hotel i work at on 19th august and im meant to be bridesmaid, dad understands how sick i am but i will get through it for him but if i take sick leave now and still show up at work for dads wedding, could they disipline me for that?
