Collective agreements are used to supplement legislation or to negotiate scope-specific contracts. The main principle is that collective agreements cannot contain terms that are less than the statutory requirements. Agreements are usually specific to the field. They include the conditions of employment of working office workers, for example. B, in the finance, IT services, construction, metallurgical and data communication sectors. Collective agreements also include decisions on working time and overtime pay. Trade Union Pro`s collective agreements include, for example, agreements on shift work differences, travel allowances, sick pay, maternity leave benefits, leave pay and child care benefits. Workers are not required to join a union in a given workplace. Nevertheless, most industries, with an average union training of 70%, are subject to a collective agreement. An agreement does not prohibit higher wages and better benefits, but sets a legal minimum, much like a minimum wage. In addition, an agreement on national income policy is often, but not always, reached, bringing together all trade unions, employers` organisations and the Finnish government.  An extremely important aspect is the limitation of the effectiveness of collective agreements in relation to the individual employment contract.
Under Article 14, paragraph 1, employment contracts can always improve the terms set by the agreements, which means that they can never be considered absolutely binding standards for individual contracts. Individual autonomy can always improve the system of collective autonomy in favour of the worker. The NNRA regulates labour relations only for companies involved in intergovernmental trade; it therefore does not protect the interests of collective agreements of all categories of workers. Several categories of employers are located outside the NRL, including those working for the U.S. government and its companies, states and their political divisions, railroads and airlines. The NNRA also does not protect certain types of workers, such as agricultural workers. B, independent contractors and managers. But other federal and regional laws often offer protection to workers outside the NRL. For example, federal employees have the right to bargain collectively under the Public Service Reform Act 1978, which is largely inspired by the NRA and enforced by the Federal Labour Relations Board.
Railways and airlines are generally subject to the Railway Labor Act, the predecessor of the NLRA. In addition, many states have adopted statutes similar to those of the LNRA, which protect the right of civil servants and local authorities to bargain collectively. British law reflects the historically contradictory nature of labour relations in the United Kingdom. In addition, workers are concerned that the union, if it were to file a collective agreement infringement action, would be bankrupted, which would allow workers to remain in collective bargaining without representation.
