A Facebook post by an employee of a non-profit employer criticized the staff for not doing enough to help the clients served by the organization. The post drew comments from five other employees who defended their job performances and criticized terms and conditions of employment. The employer discharged the five for harassing the original poster. The NLRB issued a complaint alleging the activity discussing workplace terms and conditions was protected concerted activity. A trial is set for June 22. A previous case against a different employer settled.
