Working in heat

mi

So I'm a cabana server at this indoor water park here in town, it's at a constant 87°.

My duties pretty much consist of:

Walking in average 7-12 miles a day

9 hour work days, 4 days a week.

Lifting soaking wet towels majority of the day, serving food, etc.

Is it okay to be working so damn hard ? I know our bodies are limitless (to an extent) but i just wanted some feedback !
