It’s horrible. My father works in construction and in California heat at some points he was requested to wear a mask... in the moments when even normal breathing can get hard
And the point is he worked with only two other people away from everyone else, so there was no real need
There was no one to breathe on
But if they cake and checked, well...
I’d say if the workplace doesn’t have a specific type of mask policy, maybe wear something very light and breathable? kind of just for the show. I don’t know if it works. I only put a bandana over my face at this point when I need to go into an office/market
It takes me 15 minutes to get hot and sweaty underneath, I can’t imagine working physically in it all day
