"Even though work often occupies as much of our time and energy as family, the focus of prior research and theory on the extended self has been the home. We find that negotiating the home/work boundary through personal possessions is an attempt to reconcile these competing spheres of identity," argue Kelly Tian (New Mexico State University) and Russell Belk (University of Utah).
Tian and Belk stress the importance of possessions, such as pictures, in the workplace. These not only stabilize the self, but they also allow for shifting of the self between home and work. As such, there is an inevitable blurring of boundaries. Also important is the bringing of work-related artifacts home, making a once "privileged place for privacy" less so.
"As more functional work-related possessions enter the home, more symbolic home-related possessions likely enter the workplace. Thus, we seem more apt to bring photos of family members to our office than to bring photos of work colleagues to our home."
