ECJ 6 November 2018, C-684/16 (Max-Planck-Geschellschaft), paid leave
A worker does not automatically lose the right to annual leave because s/he did not apply for it. The employer must have informed the employee about the opportunity to take the leave adequately and in a timely way, and must be able to prove it. Based on the EU Charter of Fundamental Rights, this applies between individuals as well.
