Hi, its fine. You are welcome to ask questions.
Unlike regular unemployment benefits, which is monthly based, supplementary benefits is weekly based.
This means that your A-kasse will look at how many hours you have worked in each week - and supplement with benefits up to 37 hours. This means that anything under 37 weekly working hours can be supplemented by unemployment benefit.
But note that the payout is done monthly. If you have worked so much that you can only have less than 14.8 hours of supplementary benefits (mening you have worked more than 145.53 hours, because a full moth is 160,33 hours), then you will not receive any payout in that month. The A-kasse only pays out benefits for more than 14,8 hours.
It also means that none of your weeks of work for that month will count towards the 30-week accounts for supplementary unemployment benefit.
So in your example..in October you will not use any of your 30 weeks allowed with supplementary benefits.
Please get these things confirmed by your A-kasse also.
