Rebecca Shambaugh, a leadership coach, says being too collaborative can actually hold you back at work. Instead of showing how well you build consensus and work with others, it can look like indecision or failure to prioritize. She explains what to do if you over-collaborate, how to manage someone who does, and offers some advice for women — whose bosses are more likely to see them as overly consensus-driven. Shambaugh is the author of the books "It's Not a Glass Ceiling, It's a Sticky Floor" and "Make Room For Her."
