With ex-T, when she raised rates, she kept me at the original rate, which I appreciated. I discussed this topic with current T the other day, and he said the last time he raised rates (before I started seeing him), he gave 3 months notice, and if the new rate would have been a hardship for an existing client, he'd have worked something out with them (possibly keeping them at the old rate). I think that's a good way of handling it. Or else keeping clients at their original rate.
