Oh. So it turns out it wasn't a mould induced acute respiratory attack one of the bosses was having, it was a mild heart attack.
He's still standing and upright of course, how else could he walk into my office and milk for sympathy today?
He couldn't milk for sympathy with the prior mould self-diagnosis because that would expose himself as a dickhead who only cares about himself.
I mean, it's a bad look for him pursuing the mould angle for himself while not giving a shit about the people who get exposed to the mould more days of the week than he does. Not even mentioning his respiratory attack and it's probable cause to me and giving me a health & safety heads up (in fact no one has mentioned it to me yet). The others in the other office only knew because they witnessed his respiratory attack as it happened, so he couldn't hide it from them.
It's every man/woman/other for themselves in this office I tell you.
