This study shows that a positive correlation exists between diversification of place of work and organizational commitment. The study compared the working-at-the-office group, working-from-home group, and shared-office-use group using data from an internet survey (N = 3694) and data gathered from a survey of people using shared offices (N = 424). The results were as follows. First, we found that organizational commitment was higher for the group that combined working at the office and working from home and the group that combined working at the office and shared office use than it was for the group that was only working at the office. Second, we found that organizational commitment was higher for the group that combined all three (working at the office, working from home, and shared office use) than for the group that combined working at the office and working from home. From this, we assert that diversification of the place of work gives employees a positive view of their company in that it supports them, and this could enhance employees’ organizational commitment.
