Dropped a trailer pulling away from the dock.

You absolutely did the right thing.
Accepted responsibility, reported immediately, acknowledged the fault was yours and yours alone.
Any decent manager will appreciate your honesty.

 

It has happened where sone POS pulls the release in truck stop at night.

 

Learn the proper way to park, that doesn't happen.

 

amazes me this can be an issue

 

Are you talking pull trolly handle, pull ahead till skidding, pull air knobs to keep pressure? Or what is the secret?

 

When you get parked. pull the trailer brakes. Pull forward with the tractor, and set the tractor brakes. Puts pressure on the 5th wheel, can't pull the handle.

 

Basically what I said.
