Collective agreements regulate minimum working conditions. In principle, collective bargaining agreements should never make employees worse off than the statutory minimum standards. However, collective agreements also negotiate provisions that are not regulated by law or that do not fall within the purview of legislators. These include, for example, wages and salaries, and anniversary and special payments.
