A kollektivavtal will regulate wages, for example stipulating that all employees with a certain job title must receive a salary within a certain pay band, as well as holiday allowance, overtime pay, working hours, and other benefits. That's because some things are regulated by Swedish employment law; for example, the Annual Leave Act dictates that employees must receive no fewer than 25 days' holiday, and a kollektivavtal can offer more than this, but not less. One of the main effects of the kollektivavtal is to regulate wage increases, to ensure that employees continue to get real wage increases.
