Finally, an employer or employers` organisation must reproach that the union is no longer representative of the company`s employees, so that it must report in writing to the union such an assertion, which the union has 90 days to establish itself as a representative. If the union does not find out, the employer must give the union and the workers covered by the agency contract a 30-day notice period at the end of the contract. In countries where the «right to work» applies, such trade union agreements are not applicable. Pre-agreements prevent companies from recruiting employees who are not members of the union covered by the agreement. After entry, all employees recruited by the company concerned must join a particular union within a specified period of time as soon as they have been hired. Section 25 (1) (10) presents everything related to the agency shop agreements. A boutique agency agreement is when a representative union and an employer or employer organization enter into a collective agreement. This requires the employer to deduct an agreed agency commission from the wages of workers mentioned in the agreement who are not members of the union but who are eligible for membership in the agreement. The Taft-Hartley Act banned the store closed in the United States in 1947. The trade union shop was declared illegal by the Supreme Court.  States that have the right to work go even further by not allowing employers to impose a form of union fees on workers, known as agency fees.
An employer cannot legally agree with a union to recruit only union members, but it may agree to require workers to be members of the union or to pay the equivalent of union taxes within a specified period of time after the start of employment. Similarly, a union could ask an employer who had accepted a store contract before 1947 to dismiss a worker who had been excluded from the union for any reason, but it cannot require an employer to lay off an employee of a union contract, other than the non-payment of taxes that are required of all workers. The alliances of the International Labour Organization do not care about the legality of closed store rules and leave the issue to each nation.  The legal status of commercial contracts concluded varies considerably from country to country, from prohibitions of the agreement to comprehensive regulation of the agreement to an unmentioned agreement. When a union represents a significant number of people covered by the trade agreement, it may apply to become a party to the store contract. If it is not concluded as a contracting party to the agreement and wishes to challenge the case, it may be referred in writing to the Commission. The Commission must endeavour to resolve the dispute through mediation; However, if it is not possible to do so, it may be referred to the labour tribunal for decision. The Taft-Hartley Act also prohibits unions from imposing excessively high initiation fees as a condition of membership, in order to prevent unions from using introductory fees as a means of removing non-unionized workers from a particular sector.
