Anytime there is more than one possible outcome, the option of a negotiated resolution always exists.
So the next time you’re asked, “When is it possible to mediate” or “When is a good time,” the simple answer is, “Anytime both parties are willing.”
“Even before a complaint is filed?” Yes.
While timing may affect particulars, it doesn’t foreclose discussion.
What it’s really about is getting started.
Avail yourself of a mediator versed in a variety of timed approaches, who can lend door-opening help, as well, and negotiation will be underway.
