A stoush over paramedics having to wear sweaty “shower-curtain” polyester shirts is set to come before the NSW Industrial Relations Commission. Paramedic unions say they raised concerns with NSW Ambulance a year ago about new summer long-sleeved over-shirts, which are up to 65 per cent polyester, after receiving complaints from paramedics that the shirts were causing rashes and overheating. The Australian Paramedics Association (APA) NSW and Health Serivces Union (HSU) are supporting members who stop wearing the overshirt, with the APA saying in a statement they provided employees with short-term solutions for heatwave conditions due to inaction from NSW Ambulance.
