Work-from-home writing jobs run the gamut from freelancing for consumer magazines to blogging to crowdsourcing editing jobs. Typically, work-from-home writers and editors work as freelancers. If you're already working for a company as a writer or editor, the first step may be to convince your boss to let you telecommute. Alternatively, you could always consider becoming a freelancer and look for home-based writing and editing jobs.
Virtual assistants, commonly referred to as VAs, come in all shapes and sizes. Many companies will hire VAs if they are looking for help with online administrative tasks (email, calendar management, data entry, etc), but don’t necessarily want to hire a full time employee just yet. They’re the perfect work from home job for busy people that may need to drop their work at a moments notice, or have very sporadic availability.
