If you’re currently pursuing your MBA, chances are that you hope to one day be in a position of managing your own team within a business environment. Or, you may have a goal to open your own business at some point. But as you work toward upper level management, it’s important to take into consideration all of the qualities that go into making an effective manager. In today’s ever-increasingly cutthroat work environment, a common notion among employees and bosses alike tends to be, “he who works latest works best.” And while it seems that the 40-hour work week has been largely dispensed with in our hardworking culture, new studies show that working more very seldom produces better results.
