The paper analyses the topic of unequal treatment of men and women and gender pay gaps. In the initial part, the author provides his views on the regulation of equal remuneration under the laws of the Czech Republic, as well as the causes for the gender pay gap and potential ways of closing it. In the subsequent chapter, comparison is drawn with  he laws of the United Kingdom and Hungary which contain specific provisions that may have the potential to decrease gender pay gaps (gender pay gap reporting in the United Kingdom and obligation to adjust salaries following return from leave of absence in the Hungary). The author concludes that gender pay gap represents a complex phenomenon, but can be partly fought using legislative measures, and implementation of such measures seems necessary.
