I didn't think much could shock me, but this news did:
The National Labor Relations Board ruled that a security company could ban "fraternizing" outside the job. Under labor law, theoretically employees have the right to talk about union activity -- something most bosses would prefer not be discussed -- after work. But federal law does not protect conversations about sports or the grandchildren. The First Amendment does not protect workers in this situation, as it is the company, not the government, which is prohibiting their speech. The First Amendment applies only to government and the company could legally fire workers who violate their policies.
Companies claim the policies aim to prevent sexual entanglements and exposure to sexual harassment lawsuits.
If I ever ran afoul of this sort of thing, I'd try to publicize it to the world -- this is a situation in which a boss can be made to look ridiculous. Even a management lawyer, Nate Kowalski, agreed: "In this day and age, you wouldn't expect many employers to be that stupid." Actually I wouldn't be surprised if many are that stupid -- but they probably don't want people noticing.
