MyJAM! replaces UBplusOnline on Monday April 29. From this date onwards, you won't have to search through your payslip to check how many available vacation hours you've built up; these hours can be found by clicking on the Reservations button. And your payslip? You'll discover it by pushing the button with the money bill on it (as displayed below). Within one click you'll see all the information that's relevant to you.
NOTE: this information is accessible from April 29 onwards. That means that you'll receive your first payslip through MyJAM! on the day you get your next salary. For instance: do you get paid at the end of every month? Then you won't be able to see your payslip until that day at the end of May.
