Whether or not your friends and family get a kick out of your misery at work, that online post of yours might tick off your employer. But what rights do employers have to restrain their employees from complaining about them online? Can employers punish employees for posting their grievances online? How do courts differentiate between “protected” and “tantrum” posts? What is the Government’s view on employees’ social media postings? In 2011, Pier Sixty LLC fired Hernan Perez for labeling his supervisor a “nasty M.F.” and using similarly profane language against his supervisor’s family in a Facebook post that ended with a plea to “Vote YES for the UNION.” In a 2016 decision, the Second Circuit enforced the National Labor Research Board’s (NLRB) decision and found that the employee was protected under the National Labor Relations Act (NLRA) because the post was in relation to a union-related activity.
