I would not get too worked up over the NCDOL complaint
letter. That is a standard response in cases where someone
files a complaint alleging an unsafe work environment. If
the employer ignores the direction to respond in writing,
then they may conduct an inspection (and they will likely
not be in the most helpful mood, since their request was
ignored). However, coming up with meaningful citations
would likely be difficult, in that there is not much they
could cite. If they get pissed off, then they could
probably dig up some non-mold/IAQ standards that have not
been met.
Well, there is at least one thing Dr. Thrasher said with
which I agree: "The woman doesn't know what she's talking
about." ROTFLMAF! (as the kids say)
