Iowa’s Supreme Court has ruled in the case of the job-jumping janitor. Three brothers started up a janitorial supply company in Cedar Rapids, in 1978. Three years later they hired a manager for their Davenport office, which took off and far outdid the home office in business and revenues. As time passed, the manager continued to do well, and when the parent company tried to take tighter control of its branch office, he complained that wasn’t doing the business any good. The branch manager quit, and three days later opened his own janitor-supply operation. His old bosses sued, but the Supreme Court ruled that though the original firm now has a competitor in town, their former employee didn’t hurt their company by starting his own.
