The study contains an analysis of statutory limits to the penalty of a fine for misdemeanours classified in the Act on employment promotion and labour market institutions. The characteristic feature of those sanctions is their exceptional severity. The author points out that as a result of the amendments to the provisions of the Act on employment promotion and labour market institutions introduced by the acts passed in 2017, there is an excessive aggravation of penalties for the discussed misdemeanours, and in case of two of them, the maximum limit to the statutory penalty was determined at a higher level than for some crimes. Apart from the extremely high limits to most penalties classified in AEPLMI, subject of criticism are also too narrowly established limits to some penal sanctions as well as the lack of coherence of some of them with the regulations pertaining to misdemeanours against employees’ rights and misdemeanours consisting in failing to pay contributions to other types of social insurance than the Labour Fund.
