Adjusting employment contract: What are your rights?

Questioner

I have a 3-hour contract and have been working an average of 15 hours per week for more than 1.5 years. Is my employer now legally obliged to adjust the number of hours in my contract?

Lawyer

Your employer must adjust the number of hours in your contract. Based on the legal presumption of employment volume, you can claim the number of hours that you have worked on average per week over the past three months. I have experience in working with employment contracts.
