What I don't understand is, why must the NURSES always be the ones who have to change?

Whose idea was it to allow housekeepers to wear scrubs, anyway---they're the people who need to wear different clothes. Nurses and aides should be the only staff wearing scrubs.......lab techs, unit secretaries, housekeeping staff and other ancillary personnel ought to wear something else.
At our hospital, housekeeping, maintenance, and dietary staff wear different colored polo shirts and khaki pants; only clinical staff wear scrubs. So how does the patient know who his nurse is? DUH---we
tell him who his nurse is! All staff are supposed to introduce themselves when entering a patient room, as well as explain what they're going to do. It's not rocket science, just simple courtesy........why do so many people seem to think we need to legislate that by forcing nurses to conform to some particular color scheme or uniform style??
