Working remotely requires you to overcommunicate. Tell everyone who needs to know about your schedule and availability often. When you finish a project or important task, say so. Overcommunicating doesn't necessarily mean you have to write a five-paragraph essay to explain your every move, but it does mean repeating yourself. It might also mean repeating back what you heard another person say, to make sure you interpreted their meaning correctly. Make your presence known, and don’t be afraid to ask for what you need from your supervisor and coworkers.
