Only takes one or two employees to pretend to have heat stroke/exhaustion and get a work sponsored trip to the hospital to force a change in the working environment.
Really would be safer for everyone to have someone pretend rather than wait until someone actually has one.
Most decks don’t have 12" joist supporting them… Plus, the roof appears to be cantilevered as well.
Tbh it’s hard to tell, it really looks like a house with interesting bones that got wrapped in shitty vinyl in the early 00’. But I’m not seeing any anchoring hardware, so there’s a chance that the joists are interconnected with the ones supporting the second floor.
