Is this really worth getting so worked up about. Don't you think it's actually a pity that a group of senior managers found it necessary to publish such a letter in the first place? Do you really want to work for a company that tolerates the following?
Any form of discrimination (sexual, racial, religious, age etc). . .Intolerance. . .Bullying. . .Blatant disregard for reasonable rules or conventions. . .Anything which causes offence or embarrassment to others; such offence is not measured by the giver but by the receiver. This may include subtle ostracism. . .Swearing or abusive language; it is borne of ignorance and causes offence. . .‘Bad’ behaviour may be spoken, written, or physical or covert.
It's been a difficult year for all of us, ATSAs and ATCOs alike, but being operational doesn't give anybody the right to treat others badly. This letter wasn't intended for everybody, so if you're not guilty of those behaviours mentioned, just ignore it.
