I'm on the board of a shelter with several full-time employees. For us, it's 40 hours. As you mentioned, the work can be emotionally taxing and I don't think I'd feel comfortable with a staff member working over 40 very often or very long for this reason, not because of the budget. There's a lot more to compassion fatigue than hours, but they are a big factor.
