So my wife, the music teacher, came back to her school after the summer to find that their basement classroom had a humidity of somewhere around 85% as measured by their hydrometer (string instruments are sensitive). A Co-worker had measured it as high as 95% over the summer in the heat. Mold was all over everything.
The building maintenance guy is a jackazz and thinks nothing is wrong and that maintenance will handle it. I know that not even bleach will kill mold spores, however clean it may look when you're done, and that real testing should be done when the job is complete along with the obvious dehumidifier.
My wife developed asthma over the past two years. She has worked there for four.
This is a snooty well-funded private Christian School in the area. Let's call them Christ's Moldy School.
Her boss is a politician. She will talk a good game, then go off and do whatever she wants. The headmaster is worse. Quitting (or making herself get fired by showing pictures to the parents or the newspaper) would mean that the piddly reimbursements that they've given us for her graduate education would be mine to pay, so we're talking something like 4k plus the loss of her salary. Not a small deal.
Any recourse? Not even OSHA had any regulation for air quality. I have no clue where to look for a standard, but one just has to exist.
Advice? We had a mold guy come to my house to take care of some drainage issues we had. It was pretty cheap. We can't bring the guy in without permission and I'd bet they would dismiss the test-at-home-kit results.
Nuclear option? I'll bet a judge and jury would side with the mother of three music teacher with evidence that she's asked numerous times for the humidity to be controlled and who has now developed asthma, but am I wrong?
