My T has a 1 business day notice policy, which means that since I see her on Mondays I need to let her know by Friday.

In practice, I've never had to pay for a missed session. I think the policy is in place for people who push the boundary and miss often. She's cut me slack when I've had meetings at work come up that prevent me from leaving, and even one time when I missed a make-up appointment because I thought it was at 1.30 (my usual time) when it was actually at 12.30.

I would have a hard time with a 14 day cancellation policy with no wiggle room. Life doesn't work like that. I understand that they don't get paid if we don't come, and they want us to have some skin in the game... but that's excessive.
