I currently work weekends. I have never worked weekdays in my current job and the job was advertised as weekends only. I deal with clients who use our services over the weekend but the manager at my work place has stopped clients being able to come in over weekends during the Summer and I am now being required to work Monday to Friday instead for these 6 weeks. Can they do this? I have a child who is old enough to be left home alone but I chose these hours so that I would be there during school holidays.
