As part of your practice, you allow clients to contact you via your work cell phone until 8pm at night. A client calls you at 7:45pm to discuss a problem with you, and later asks if they can call you back at 8:30pm because they are leaving to run a quick errand. You very much value your time in the evening to spend with your family at home, and want to create better work/life balance. Because the client indicated they are not in crisis and you want to model the importance of respecting established boundaries, you decide to tell your client that they will have to wait to contact you until the following day.
