Wayne Baker, professor at the Ross School of Business at the University of Michigan, has spent much of his career researching the best way to effectively ask for help at work. Whether you're soliciting support on a tricky assignment or more resources for your team, it can feel uncomfortable to approach bosses and colleagues with hat in hand. But we rarely get what we need or want without asking for it. Baker highlights some of the most effective strategies for defining your goal, figuring out who to ask, and crafting your message so it will be positively received. He is also the author of the book “All You Have to Do Is Ask: How to Master the Most Important Skill for Success.”
