Only do what Surt suggested if you are NOT in a two-party consent state.
When must you get permission from everyone involved before recording?Eleven states require the consent of every party to a phone call or conversation in order to make the recording lawful. These "two-party consent" laws have been adopted in California, Connecticut, Florida, Illinois, Maryland, Massachusetts, Montana, New Hampshire, Pennsylvania and Washington. (Notes: (1) Illinois' two-party consent statute was held unconstitutional in 2014; (2) Hawai'i is in general a one-party state, but requires two-party consent if the recording device is installed in a private place; (3) Massachusetts bans "secret" recordings rather than requiring explicit consent from all parties.). Although they are referred to as "two-party consent" laws, consent must be obtained from every party to a phone call or conversation if it involves more than two people. In some of these states, it might be enough if all parties to the call or conversation know that you are recording and proceed with the communication anyway, even if they do not voice explicit consent.

I'd record him, then later shoot a 3rd co-worker that he also had beef with and the next day at work I'd be; 'Oh, I actually have this recording of Greg talking about his guns to me last week.' to the police, then they'd search his home and find the gun I stashed in his linen closet. Greg's in jail, Sharon's dead and Samhain has a sweet new corner office.
