I also recommend FlexJobs for finding more home data entry jobs. With that site, you can regularly search legitimate work at home jobs for data entry and other industries. Every job lead is guaranteed scam-free, and it's the only membership-based jobs site I currently use and trust. Their listings are updated 5-6 times per week, and they are plentiful. You can currently get 30% off a subscription using promo code AFFILPROMO.
A work from home job can be any position that does not require you to be in an office. There a wide range of work from home jobs. Some companies offer opportunities for employees in traditional roles to work remotely for all or some of their workweek. These jobs often use technology for meetings, assignments, and collaboration. This practice is called telecommuting. Other work from home opportunities may include jobs such as customer service representatives for which companies will hire remote workers, or part-time virtual assistants to manage work which does not require a physical presence in the office.
