Asıl metin - Hırvatça - Å tovani, Obiteljski i zdravstveni razlozi naveli...

"Family and health reasons made me decide not to sign a new contract with GPDubrovnik d.d.
I would like to be granted a severance pay according to article 17. of the 01.01.2004 Contract.
I am at your disposal regarding work within my expertise and abilities until the conclusion of my employment.
Of course within that period I would like to be able to use my vacation days for the year 2006."

The title also uses the word "Å¡tovani" which means "respected" but it's the generic start of every letter like "dear sir" or "dear madam" so use whatever is common in Dutch business letters.
