Not that it is exactly relevant to this thread,
but all the mine disasters since 2000 (and possibly
before) all happened in non-union mines. Especially
after the previous 3 which happened pretty close
time wise, the UWMA could have easily won the hearts and
minds of Americans and unionized those mines. Interesting
that despite it's status as a non-union mine, the Union
sent out its expert rescue and safety team which is doing
most of the work.
