The number of companies that have taken disciplinary action against employees for conducting inappropriate behavior on social networking sites has doubled from 2012 to last year, according to a recent survey of more than 100 international companies conducted by Proskauer Rose.

The firm, which on April 29 released a new edition of its annual report called “Social Media in the Workplace Around the World 3.0,” said the misuse of social media among employees is skyrocketing from previous surveys in 2011 and 2012, where approximately 31 and 35 percent, respectively, of some 250 multinational business respondents reported misuse to more than 70 percent in 2013, according to Proskauer data. The firm said the uptick in misuse is because social media platforms, such as LinkedIn, Twitter, Facebook, Instagram, Pinterest and others, are currently used by nearly 90 percent of businesses.
