I work in automation. We had one site in Florida that despite AC pumping all the time, had humidity issues. Electonics seemed to handle it ok, but paper was another story. This site would have to print information packs to get packaged up with the product, and it was a nightmare with the collating and folding automation, it just never wanted to work properly. The printers themselves would jam and have more issues than they should as well.

Having worked for UPS in the past, these guys definitely earn it. Long days, boiling hot or freezing cold, and wrecking their bodies the entire time.
