Janice complains that her husband, Arnie, is a workaholic. Arnie is so focused on productivity at work that he rarely has time for her or the children. Furthermore, she knows that he has missed important deadlines recently and cannot understand how this is possible, given the number of hours he works. When Arnie is at home, he is demanding, controlling, and angry with Janice if things are not done to his specifications. What personality disorder would Arnie most likely be exhibiting?
