While I must agree with most of your comments, I would prefer to write to the bosses directly; it could be more effective 
My guess is that you haven't been here very long.
Writing to EK management, in the hope of effecting positive change, is probably the most futile pursuit I can think of right now.
But by all means try your hardest.
