The DOJ and FTC state that any agreement limiting hiring between employers that are competing for the same employees is a per se antitrust violation that may result in civil or criminal liability...After lots of fuss RJ and Elon will sign some sort of agreement agreeing not to poach each others employees.
Highlights:This article covers the Tesla complaint in more detail:
On July 7, 2020, after her conversation With Duran and the same day that Wong received an update on her background check by Rivian, she sent at least sixteen highly confidential and trade secret recruiting documents from Tesla’s network to her Gmail account, including various guides and templates developed by Tesla—the very types of documents that Duran had instructed her that Rivian needed.
These documents consisted of highly sensitive trade secret, confidential, and proprietary engineering information about manufacturing project management, controls specifications for manufacturing equipment, specifications regarding manufacturing robotics, and manufacturing equipment requirements. These documents would be used rarely, if at all, by Siron as manager of Environmental Health and Safety, yet she exported them shortly after accepting her offer at Rivian.
