I must admit I do favour shorts sleeves ,no tie etc. The shirt with the organisation's logo and department embroidered on the breast to signify that you are a staff member & waht department you belong to. If protective clothes should be worn then apron,gloves, facemask if required, should be part of standard procedure when deling with possible contaminated equipment.
How many docs & consultatnts do you see walking about with a white coat on. As far as I'm aware the "white coat" is blamed for the transmission of infection anywy and should be discarded in the bin along with other antiquities that we seem to hang on to.
