I respectfully disagree. Examples abound where employers should be notified and disciplined, if the employer deems it appropriate.
Several months ago
bdschobel alerted DL to an employee poster who threatened that he/she could do unspecified harm to the members who don't try very hard to remain anonymous, like Bruce. Should Bruce have been disciplined for his justifiable conduct?
No disclaimer legally protects employees who post here once they have disclosed the identity of their employers, and that includes employees of the US government.
Further, your proposal attempts to regulate conduct that does not directly impact FT. Additionally, your new rule would only punish members who disclose to the community that they reported a FTer to the alleged employer - while not touching a member who reports on an employee but makes no such announcement to the community.
So if I "tell on" a member, I've only violated your new TOS rule if I let FT know what I did.
I'll think of other objections later, these are just the five minute answers.
Don't want members trying to get other members fired or disciplined? Teach people to keep their employers a secret. Disclose too much info, you make yourself vulnerable.
