A new survey finds that employers and employees don’t see eye-to-eye on the role of social media in the workplace, a new Deloitte LLP survey suggests. For instance, 45 percent of executives said social media has a positive effect on the culture of their workplaces, while only 27 percent of employees agreed. Also, 38 percent of corporate leaders said they thought social media generated more transparency in the workplace, compared with only 17 percent of employees.
