Whenever it is charged that any person has engaged in or is engaging in any such unfair labor practice, the board, or any agent or agency designated by the board for such purposes, shall have power to issue and cause to be served upon such person a complaint stating the charges in that respect, and containing a notice of hearing before the board or a member thereof, or before a designated agency or agencies, at a place therein fixed, not less than five days after the serving of such complaint. No complaint shall issue based upon any unfair labor practice occurring more than six months prior to the filing of the charge with the board and the service of a copy thereof upon the person against whom such charge is made, unless the person aggrieved thereby was prevented from filing such charge by reason of service in the armed forces, in which event the six-month period shall be computed from the day of his discharge. Any such complaint may be amended by the member, agent, or agency conducting the hearing, or the board in its discretion, at any time prior to the issuance of an order based thereon. The person so complained against shall have the right to file an answer to the original or amended complaint and to appear in person or otherwise and give testimony at the place and time fixed in the complaint. In the discretion of the member, agent, or agency conducting the hearing or the board, any other person may be allowed to intervene in the proceeding and to present testimony. Any such proceeding shall, so far as practicable, be conducted in accordance with the Evidence Code. All proceedings shall be appropriately reported.
