Safety at 141 school

HI:

If I've posted this to the wrong group, please forgive me and point me
in the right direction.

I am employed by a Part 141 flight school. There is an employee here
(working as an AC dispatcher) that has been caught in numerous safety
violations. Ususally, it's assigning an AC to a student while that AC
is currently under a "maintenance hold". This of course has
potentailly disastrous consequences.

We have a computer system that helps protect against such mistakes from
happening, but this person is so "clueless" that it doesn't matter.
They just keep making the same mistakes over and over.

I have brought this to the attention of senior management at the
school. However, for some reason they seem reluctant to do anything
about the situation.

The person involved has numerous complaints against them from
instructors and students alike. I am beginning to think I should get
the FAA involved before someone is hurt or killed. The safety
violations are documented, but only "unofficially". I suspect that if
the FAA comes calling, my management will simply destroy any evidence
and claim there is no problem.

This person really needs to be fired for total incompetence, but if I
"blow the whistle", I can probably kiss my own job goodby.

Any thoughts/opinions??
