Letting your boss be
You’re hard at work on a project and rather than check in with your boss along the way, you’re keeping out of his or her hair until the project is done. But unless you know this to be your manager’s preference, you risk serious under-communication. If the project isn’t done correctly and has to be reworked, that’s plenty of time and energy wasted, which won’t look good. Your boss may begin to question your judgment in other areas, too.
