Hey Robert, Welcome to HW we are glad to have you join us here. If your wondering about this because of depression then I imagine it would be difficult to go to an employer and ask for a reduction in hours or work load without having to have some sort of legal recourse. Of course this would depend on your employer and your job...but, even in this day and age depression still isnt a well recognized illness by employers though it is a medical illness.
I hope you get some input from members who have been in this type of situation so they can give you some ideas on what your asking. Keep posting
