27The right to paid annual leave is, as a principle of EU social law, particularly important, as is apparent from the fact that it is expressly enshrined in Article 31(2) of the Charter. It should be recalled that Article 7(1) of Directive 2003/88 reflects and gives concrete expression to that fundamental right to an annual period of paid leave, as enshrined in the Charter. While Article 31(2) of the Charter guarantees the right of every worker to an annual period of paid leave, Article 7(1) of Directive 2003/88 implements that principle by fixing the duration of that period (see, to that effect, judgment of 22 September 2022, Fraport and St. Vincenz-Krankenhaus, C‑518/20 and C‑727/20, EU:C:2022:707, paragraph 26 and the case-law cited).
