Giving this a little perspective, it is just the trust buildings he was prohibited from entering and due process was followed by management, witness statements and a meeting ( which he neglected to attend) he had ample chance to explain his version of events but chose not to.
He is still rightly entitled to free speech as network rail have stated the ban does not extend to the railway station in it's entirety, the issue was on trust property any therefore an issue for them and their codes of conduct alone.

All organisations have these, they are not a court of law therefore I don't understand the comparison.
