Aplumber working for a company providing plumbing services to commercial and industrial establishments was required to be “on call” for emergency plumbing services 24 hours a day, and was required to drive his company van home each night so he would have all of his tools and equipment at hand for any calls. however, he was not permitted to use the company van for personal errands. on his way home one afternoon, he took a detour toward a supermarket a few blocks away to pick up some items for dinner. while entering the supermarket parking lot, he drove negligently and struck a pedestrian, seriously injuring him. the pedestrian filed suit against the plumber’s company in a jurisdiction that maintains traditional common law rules regarding contribution and indemnity, and the jury awarded him $100,000 in damages, which the company paid. if the company sues the plumber to recoup its loss in the lawsuit, which party will prevail?
