A friend of mine started work as a care assistant a week ago. She goes to work on Monday afternoon and finishes Wednesday afternoon and sleeps over the two nights. She is "on duty" for 26.5 hours over the two days, including 4 hours of time off in total. This does not include the hours that she sleeps there. She cooks, cleans and generally looks after a patient who is completely immobile. (She has help with moving the patient). She is being paid €200 in total. This works out at €7.5 per hour but the time she must sleep there is not included. Is this legal?
