In my country, most if not all therapists in private practice work evenings, at least some days of the week, for this exact reason. On the other hand, I am subscribed to a US-based practice building newsletter that teaches therapists to only accepts the clients they want, for the fees they want, at the hours they really want to work. I'm aware one newsletter doesn't represent a very big country, but the reason the author suggests this is because there are many potential clients and that the "whole reason" for being in private practice is to choose one's own working hours for a better work-life balance. Now, in my country, psychotherapists usually work in private practice because there are no mental health agencies, just some very low-paying jobs in NGOs and mostly psych clinics that require the therapists to have a private practice and pay their own taxes so the clinic won't have to take the responsibility of employing them. So then in a way it makes sense to me that therapists in private practice here where it's pretty much the way to go in this profession, will tailor hours to the clients needs more than therapists who had a choice and preferred private practice to set working hours at their own convenience. Still, I think there should usually be at least some flexibility. In my country, there are actually some therapists in private practice who still work at their day jobs and work as therapists from 4 or 5 o'clock in the afternoon.
