OK, let's assume the employees are informed... and do understand !
The best safety measure would be to put the offices of the CEO
and all other management in the middle of the factory, with no
special protections other than what the employees have.
And putting a day-care for the children of managment employees
in the same area might help too
.
And requiring all management to live in the community, down-hill,
down-stream, and down-wind of the factory.
Also, an insurance/college fund for the families of the production staff,
in place and not accessible to management/fiscal procedures,
would also be a reasonable requirement of the company... just in case
