Most hands-on care roles don't have 9-5 hours, unfortunately, as most people need help early in the morning to get up and ready for the day, or for afternoon, evening, or night calls. Most of the time, you can have a discussion with a care employer about a work pattern that suits you as well as the clients' needs, though.
There are also a variety of office-based jobs in homecare that are much more 9-5 friendly!
