Pros
Zirtual provides an employment opportunity to people who need money and have limited options. Working from home, at Starbucks, etc., is convenient and eliminates commuting costs. A number of people seem to be able to work successfully while watching small children, although others indicated that they found that difficult.
Cons
Zirtual seems to be selling a personal relationship with you to anyone with a debit card and a couple hundred dollars. While its advertisements suggest the contrary, in my experience its clientele seemed to be more along the lines of random people off the street than off Wall Street; you must nonetheless provide your name and background information to anyone to whom they assign you -- you have absolutely no say with respect to who you work for -- and client assignments appeared to me to be based solely on availability. Services to be provided are specifically outlined on Zirtual's website but I was expected to do things that were not on the list. Individuals assigned to me were in my view often abusive, petulant, of limited intelligence and/or mentally ill and, while management persuasively maintains that it will "have your back" with respect to such clients, I did not find that to be the case. You can be terminated without notice or severance and satisfying the demands of clients and management may require you to work more hours than those for which you are paid. Management seems inexperienced but nice and they talk a very good game, but I grew weary of the excuse that they didn't seem to know what they were doing because the company "was a startup."
