Of course you can! This is not something that is governed by us or your training contract, it's the right of every employee under Dutch law.
But we feel that It's very important you are happy in your job and your workplace.
What happens if I quit?
Provided there is still training costs to recover from the overall total, we will continue to help you obtain work with another suitable employer. In turn, you as the graduate will also do everything within reason to find employment with another suitable employer.
