Pros
Management and employees seem to be very nice people and there are places to go for help in dealing with difficult or unusual requests. Excellent training program. For stay-at-home moms or retirees, it's a good way to earn a little extra money from home while saving money on car, wardrobe, and/or daycare expenses.
Cons
Clients come and go A LOT, for reasons you have no control over, so the amount you make varies from month to month. Zirtual operates on a Walmart model (low prices, low wages, high turnover of both clients and employees), so don't expect to be able to support yourself on what you make. You are expected to be available all day during regular business hours, but are only paid for "active" time. Even one demanding client means that the much-touted "Zirtual Lifestyle" of freedom to schedule your tasks and be available to take the kids to the park after school goes right out the window.
