One of the things that surprised me about Google's employee agreement was that by signing it, the employee gives permission to Google to search any and all digital devices associated with the employee whether or not they are owned by Google. When I asked an employment lawyer about it he suggested it was fairly boilerplate (if a bit extreme) and designed to combat situations exactly like this, party A sues the employer based on behavior of employee B who may have been doing nefarious things 'off book'.So in this case Uber presumably has a similar clause in their employment agreement and are searching relevant employees devices for evidence of the files.
