My preferred attire would be T shirt on the cold days, bare chest on warm days, Bermuda shorts ( something short with pockets ) and that's pretty much it, maybe shoes if the ground are warm.
But it would also be nice to be in a place where you could go and take a dip in a ocean if you like to.
It is of course problematic to work in a environment like that, the times i have worked in such a environment, well no one expected a full 8 hour working day unless there was a break down, and then it was all hands on deck, so you could instigate a cool down rotation in the control room.
Cuz working in 40 - 50 degrees, that's not child's play its pretty dangerous., and actually under Danish work law temperatures around 32- 35 workers must have more breaks and a option to cool down.
But in day 2 day work standing temperatures must be 25 MAX 18 - 22 degree C recommended.
If relative air moisture go over 60% more breaks and a place to cool down are a right of the worker.
If the work force the worked to wear heavy clothes, the brakes must be more frequent and even longer.
We dont have siesta which was a little hard to explain to a Mexican that also worked where i did powder painting, and really that was not needed.
But at least i dident bully him like others did, actually i went and told them to lay off the guy, and then i demonstrated my meager grasp on the Mexican language and told him i n Mexican the other guys are so and so people.
And in return i learned a little more Mexican.
and gained a friend.
