(1)In the case of an agency tender official who is an interested party under section 3551(2)(B) of this title, the official may file a protest in connection with the public-private competition for which the official is an interested party. At the request of a majority of the employees of the Federal agency who are engaged in the performance of the activity or function subject to such public-private competition, the official shall file a protest in connection with such public-private competition unless the official determines that there is no reasonable basis for the protest.
