69. Chris, Bill, and Leslie are attempting to initiate an authorization card campaign at Cover-the-Earth Enterprises, Inc.'s (CTEE) Oxford, MS facility. The facility, like all of Cover-the-Earth's plants, is a limited access facility. Bill is a professional union organizer who is a full time employee of the Labor's International Union of North America (LIUNA). Chris is a production worker on the evening shift at CTEE and a new member of LIUNA. Leslie, Bill's fiancée, is a production supervisor at CTEE on the evening shift. On March 16, 2017 at 8 p.m. (during the meal break of the evening shift), Bob Robinson, plant superintendent, and every employee's worst nightmare, finds all three friends handing out union organizing materials to employees in the company break/lunch room, while singing Solidarity Forever. Which individual(s) cannot be disciplined or fired?
