Carers carrying out a home visit refuse to wear slippers or take off their outdoor shoes due to health and safety. The householder bought slippers for each of the carers to use but they refuse to wear them and their outdoor footwear is leaving dirty marks on the carpets.
Employers will have provided the carers with/require them to wear sensible footwear which take account of the type of work they are likely to do on their "rounds" eg lifting or carrying. Simply trotting out "health and safety" as the reason for rejecting the slippers is not helpful. This problem could be easily solved to everyone's satisfaction by the carers having a supply of plastic shoe covers to wear indoors to protect the resident's carpets.
