Facebook's board is in some serious planning mode. According to a recent filing with the Securities and Exchange Commission, in case of stepping down from management or getting fired from the company, Mark Zuckerberg, Founder and CEO of the social media giant, may have to lose control over the company. In the regulatory filing, Facebook shared the dates for its annual general meeting on June 20 where shareholders will be asked to vote on a proposal that would "ensure that we will not remain a founder-controlled company after we cease to be a founder-led company."
