I disagree that this is universally true. I have had at least 2 bosses that I know would help deal with burnout because 1 of them helped me and the other I have seen help others in this same situation. A good boss cares about their employee's health and wants to keep good workers. I agree that your advice is the safe route, but I think if you know for a fact you have one of the good bosses of the world then that approach can lead to better results.
