I recently purchased some company branded polo shirts for the staff to wear, but the staff are complaining that they are too hot wearing them. I personally don't think the polo shirts are too hot, but I would say they are not the most breathable fabric I've come across. Staff are also allowed to wear shorts if they want. But some staff are wearing trousers, thick cotton tops, or thin cardigans to work! What's the best way to deal with this? I've had many jobs where I've had to wear a shirt, trousers, and waistcoat during the summer, with no AC. I would have loved to have been able to wear t-shirt and shorts to work! I get that uniforms are not always the most comfortable piece of clothing, but they give us that much more professional look.
