Part-time workers may claim additional pay for overtime and ther pro-rata payments

In the discussed case, the court investigated whether working time must be considered when determining workers’ remuneration.

Additional remuneration and bonuses must be equally accessible for all employees. – Sławomir Paruch and Oskar Kwiatkowski comment for Dziennik Gazeta Prawna.
