I'm the Manager of 2 day centres for elderly people. I love it. One is on Tuesdays, just the afternoon, and the other is all day on Fridays. I arrange all the entertainment (guitarists, singers, magicians, etc), and I oversee what the cook, the finance person, the 3 volunteers all do. I hire and fire people too , and hired a care worker to help people with toileting needs.
I buy the gifts for birthdays, Christmas and any other occasions. I also decorate the place up for events we have (Easter, the Royal wedding, Remembrance Day, Christmas, etc), and buy all the food and drinks for those occasions. I organise outings. I absolutely love the job. It is so rewarding, and I really get to know the people who attend the day centres....several of them ring me just for a chat, and I go and visit them if they're ill.
I think all care work involves working shifts and weekends.
