What are my employee's rights when it comes to workplace temperature? I have a warehouse with several employees, all of them are fine in cooler weather like today where it is 11c. I supply staff with any clothing they want including heated clothing which works perfectly especially as each person can adjust the temperature to their own needs but I have one employee who will only wear a t-shirt, ripped jeans and his own jacket unzipped which is thin so it does little to keep him warm, even if it is zero degrees he will wear the same clothing. When he complains its cool, we ask him to at least zip up his jacket but he won't. I've asked him why he won't wear anything else and he says he feels everything feels restrictive, he won't even wear a loose hoodie, I think part of the reason is also that he dislikes the style of most clothing. Generally, we avoid using the heaters unless it is actually cold due to the cost and size of the warehouse plus heated clothing does the job better anyway as the heat is direct. The heaters can add up a lot especially as he is the only person who needs them and in some cases, he will use them when it's very mild say 17c yet some staff complain it's warm as they are moving stock all day. As far as I can see there is no actual rule on this, we've spoken to him several times but can't come to an agreement and I don't want to come across as draconian telling him he can't use the heater.
