Good morning.Can I ask an advice about my situation?I have a limited contact and it will end May of next year.My workplace is already open for almost a month now but then I was put on hold for unknown reason.I keep on messaging the management that i really need to back to work since September they didn't give me salary.Last September 1 they told me to sign a paper stated that i am on leave without pay.and another paper i sign dated September 29 stated that i am still on leave without pay until the ministry of Education will give an approval for opening.
