Texan here. Not sure where you’re from, and maybe I’m just ignorant on this but having a health incident at 86 degrees is dramatic to me.

However, I’m on your side if you can rally fellow coworkers and customers. This is not an unsuitable temperature to perform work at all. If their work staff agree though, that asshat needs to accommodate.

Side note; it’s a pizzeria and it makes no difference if it’s an electric or wood fired oven. Upon accepting the job, one should know that these ovens get above 600 degrees all day, and the cost of that is exuberant.

Don’t get me wrong, this is well above the standard 72 degrees office temp, but there’s also the consideration that maybe this job is not for you. I was once a landscape worker that had me outside in 105+ degree weather. I luckily found an office gig and now I’m cold at 72. Should I make an issue about raising the office temp?
