My therapist's cancellation policy is a little unusual in that he doesn't have one... Or if he does, he's never expressed it to me. I've always been able to give him at least a week's notice (often two or three) of needing to miss or reschedule a session, and when a couple of serious emergencies have arisen he's let me know that canceling last minute was fine with him if needed, though it hasn't been needed so far. I do wonder sometimes if his no-policy policy is an across the board thing, or whether he accidentally forgot to mention it when I started seeing him and it's just never come up since.

A 14 day cancellation policy would definitely stress me out! Even though I'm generally able to give lots of advance notice, I do have work schedules shift sometimes at less than two weeks away. And every other therapist I've seen had a 24 or 48 hour policy, so 14 days is definitely a real outlier.
