Title 29 › Chapter CHAPTER 7— - LABOR-MANAGEMENT RELATIONS › Subchapter SUBCHAPTER II— - NATIONAL LABOR RELATIONS › § 158
Makes it illegal for employers to stop or punish workers who use their rights under the law, to run or secretly fund a union, to treat workers differently because of union membership, to fire someone for filing charges or giving testimony, or to refuse to bargain with employee representatives. An employer may allow workers to talk with a representative during work time under rules the Board makes. Employers can agree with a union to require membership after the thirtieth day of work or the start of the agreement if the union is the workers’ chosen representative and certain election conditions are met. Employers also must not discriminate if they reasonably believe a worker could not join or was kicked out for reasons other than failing to pay regular dues and fees. Makes it illegal for unions to force or scare workers or employers, to cause employer discrimination, to refuse to bargain if they represent the workers, to push certain kinds of strikes or boycotts that affect commerce, to charge fees found excessive, to get employers to pay for services not done, or to picket to force recognition except in limited situations (for example, if another union was lawfully recognized, if a valid election happened in the past 12 months, or if no petition is filed within 30 days of picketing). Speaking or printing opinions is allowed if there is no threat or promise. “Bargaining collectively” means both sides must meet at fair times and try in good faith to negotiate wages, hours, and other terms, and sign a written contract if asked, but neither side must agree to any proposal. To change or end an existing contract, a party must give 90 days’ written notice, offer to meet, notify the Federal Mediation and Conciliation Service and the state agency within 60 days after that notice, and keep the contract in force for 90 days after notice or until it ends. Special rules let construction employers and unions make certain agreements and require unions at health care institutions to give at least 10 days’ written notice to the facility and the Federal Mediation and Conciliation Service before any strike or work stoppage.
