Wiz mate, it's not right, legal or ethical and the reason this industry is still eating its own young at the same time as complaining about the rates.
Bendo is right.
First thing you can do is get ALL the staff into your office tell them that there have been some breaches of confidentiality, explain to them the illegality of it and consequences and ask them to ensure that their own conduct is exemplary. Explain to them that it is every employees duty to ensure that information they receive as a employee or as part of their employment is confidential to them and the company which employs them. That confidentiality also extends to their families and friends.
If you can get the evidence on diverted faxes, quotes etc, take it straight to your lawyer and get him to sack (misconduct) and sue the insider and the receiver (stolen property) and lay charges if you can. It's not CASA's problem it's yours. And ask your leagle how to tell the clients who's privileged information has been disseminated that they have been compromised, by and too whom and that you have taken action for their dismissal.
Scuttlebut, rumour or nod and wink aren't good enough and that is why it is so hard...........BUT........... if the employee is dumb enough to pass on confidential information and the other guy is dumb enough to receive it, they WILL trip themselves up, you just need to be patient.
You may be surprised how seriously your clients take it and appreciate the tip off. Just be sure you have the facts right and your lawyers advice.
Unfortunately these morons last long enough to take every body else around them down with them.
Unfortunately and I have been there it is too often your own staff/pilots who are the culprits, they spend more time with your clients than you do. Brief your clients that your quoting/price information is confidential to them and that for reasons of confidentiality is not revealed even to your staff/pilots, only to those who have a legitimate use for it.
Answer equals, tell em
absolutely nothing except what they need to know where they are going and who they are taking. Keep all your company details, prices, quotes and costs etc. within your sight or otherwise under lock and key, password your computer and keep your filing cabinets locked. Tell em
NOTHING about your future plans or future equipment. ZIP NADA, NOZZINGS. It's hard in a small office, but you can also rest assured that the ones who know the rules will not be the ones who want to know. If they have been brought up proper
they would too embarrased to ask in the first place and if they haven't come from a commercial background they will only need to be told, nicely, once.
Trust no one. It's none of their, business anyway.
