Plus, you face the possibility of discrimination lawsuits from rejected internal applicants. Here are six common rehiring mistakes:

Plenty of organizations offer flexible schedules, allow telework and let parents slip out early once in a while to catch a child’s soccer game. But in many workplaces, those benefits are perks that only managers and white-collar workers enjoy.

If your organization’s lower-wage employees are candidates for flex, consider these eight strategies.

Miami-Dade County has agreed to settle a long-running legal dispute with the Wackenhut security firm, and one of the biggest winners is a Wackenhut worker who blew the whistle on the company.

Ever since the EEOC began tracking discrimination complaints, race bias has been the most popular claim. Not anymore. Claims of employer retaliation now top the charts—33,613 claims in fiscal 2009.
