If you have 8am class definitely must be in classroom before 8am right?
Working in ITE is meaningful. Once in a while i do get students who texted me and tell me their progress in poly, ns or work.
Once a couple of them even wrote a letter using pencil to say how much i was like their father. I think that is the motivation for all teachers rather than the salary. And remember, students are in ITE for 2 years, so no matter how bad they are, they don't learnt that in ITE, they got it from secondary school or poly. And if we manage to groom or inspire some, i think that calls for a celebration.
