As a starting point, you use 1 of your 30 weeks' supplementary unemployment benefit when you work part-time (between 1 and 36 hours) in a week.
We use the start and end date that you specify in your assignment as well as the total number of hours in your employment contract, which we draw up and which you hand in to your unemployment insurance fund.
This means that if you have a task of, for example, 37 hours, which starts on Monday and ends, for example, on Sunday, then you do NOT use supplementary unemployment benefit. If you have an assignment of 37 hours that starts on Wednesday and ends the following week, you will use 2 additional weeks.
On your daily allowance card, you can state that you do not wish to receive supplementary daily allowance for the week in question. Perhaps you have worked 35 hours and do not want to spend one week on 2 hours of unemployment benefit, while the following week you have worked 4 hours and would like to be supplemented.
You can have up to 145.6 hours per month (equivalent to 33.6 hours on average per week) and still receive supplementary unemployment benefit.
