Your Polish employer has to pay social security costs and compulsory insurances to the social insurance office (Zaklad Ubezpieczen Spolecznych) and to the National Health Fund. Since individual cases can differ greatly we recommend you get more information at www.zus.pl.
When negotiating your salary, note that these fees get subtracted from your gross salary. Since the incidental wage costs can make up about 40 per cent of the gross salary, it might be better to calculate what your net wage should be. Your net wage shouldn't be less than 2.000 PLN unless you have additional income.
Sick pay is available in Poland, starting at the 28th day of the illness. For the first 27 days of a sickness there is no social benefit. Your employer can freeze your salary after four weeks of being ill. Therefore it is recommended to have extra insurance.
Maternity leave in Poland entitles to 18 weeks for the first child. With every subsequent child this period is extended to 20 weeks. In case of multiple births you are entitled to 28 weeks off.
For every newborn baby parents get a one-time payment of 1000 PLN. In general everybody is eligible to receive that payment although in reality it may be hard to get. Child allowance, paid for every child on a monthly basis, is around 40 PLN.
