The problem of parasitism is often used to justify union safety agreements. A classic study on the problem of parasitism is presented in Mancur Olson`s 1965 work, The Logic of Collective Action.  In labour relations, there is the problem of parasites, because the cost of organizing a union and negotiating a contract with the employer can be very high, and because employers will find it too expensive to take on multiple pay and benefit scales. , some or all non-union members may find that the contract is also favourable to them.  Therefore, the incentive is for individual workers to “drive for free” by not paying the fees, which can lead to the collapse of the union and the absence of a collective agreement.  If the union collapses, any worker could be worse than if the union had negotiated the contract.  Eu security agreements are a means of ensuring that all (or almost) workers bear their fair share of the cost of collective bargaining (for example). B union membership and dues).   One solution is for the state to provide rights (such as the right to manage social or pension funds or participation in an enterprise committee) or benefits (such as unemployment insurance) only for unions or their members.
  Another solution is for unions to conduct collective collective bargaining that limits the benefits of the contract to union members.  The LNRA allows, under certain conditions, a union and an employer to enter into an inter-union security agreement requiring workers to make certain payments to the union in order to keep their jobs. Janus v. American Federation of State, County, and Municipal Employees, Council 31, US (2018) is a case of U.S. labor law in which it comes to whether governments violate the First Amendment when they ask their employees to pay union rights as a condition of employment. The EU`s security agreements are explicitly mentioned in the labour laws of many countries. They are heavily regulated by laws and court decisions in the United States and, to a lesser extent, in the United Kingdom.  In Canada, the legal status of the union security agreement varies from province to province and at the federal level, with some provinces allowing it but not claiming it, but the majority of provinces (and the federal government) required it when the union required it.  There are different types of union security agreements. Among the most frequent, in June 2018, the U.S. Supreme Court ruled in Janus` favor in a 5-4 decision and stated that “states and public sector unions can no longer deduct agency fees from workers who do not accept.”  However, when non-members object to the use of their payments for non-representative purposes, most of them are likely to bear their share of the union`s costs associated with advocament activities, such as collective bargaining, contract management and complaint adjustment.
