Employees show a significant decline in exerted effort when they are informed about the futility of a task already done. As the results of an experiment conducted by Sabrina Jeworrek from the Halle Institute for Economic Research (IWH) and co-authors show, meaningless work causes anger and disappointment, and can negatively affect employees' later motivation. However, employees seem to “forgive” their employer for cancelling a project if another and still valid purpose is credibly communicated.
