Hi,
The rule about losing your Unemployment benefits in case you stop job by your self again within 12 months, only applies if you already have a current quarantine in your A-kasse.
The A-kasse will only give you 1 time quarantine (3 weeks), if you quit two jobs at the same time.
If you have a quarantine for self-inflicted unemployment and you are self-inflicted again within 12 months, you will lose unemployment benefits until you have 300 pay hours reported to the income register within a continuous period of 3 months if you are paid monthly or 276 pay hours within a continuous period of 12 weeks.
Best regards,
Anders, www-a-kasser.dk
