If you have not received your salary on the 25th it is because you have not registered your bank account with Swedbank's account register (Kontoregister). Please do this as soon as possible to be able to receive next months payslip in time.
If your account is not registered you will recieve a check by post on the adress you have stated on your contract. Ususally it arrives on the same week as the 25th. If the check has not arrived we kindly ask you to contact Flexios' support in the chat.
