Is it time to say no to shadow work?

You can call it self-service, or you can call it no service at all -- we scan our own groceries. We pump our own gas. We're our own travel agents and bank tellers. Those innumerable unpaid jobs we do every day have been dubbed shadow work.

Harvard Magazine deputy editor Craig Lambert says that while some self-service is a fine thing, the volume of shadow work today amounts to countless hours of invisible, unpaid extra work for your average person.

How do you feel about your shadow jobs? Is it time to reject all that unpaid work? Or do you appreciate the greater efficiency of just doing it yourself?
