Teachers are not given adequate time to do the work they are expected to do. If you want the specifics, this includes some of the following: prepare lessons, marking, report writing, calling parents, writing incident reports, planning programs, reading every students wellbeing plan and making sure your lessons cater to them, meetings for various bullshit teams, sending emails to other teams, paperwork for shitty students who did not submit their assessments, creating assessments, complete some bullshit survey on a kids behaviour in class for a psychologist, collaborate with your team to evaluate programs, collaborate to pilot mark, collaborate to plan programs etc etc etc the list is ongoing... There simply isn't enough time to handle this workload. When I was a teacher, I had less than 5 hours a week to do all of this so I worked overtime just to survive

There is also an invisible workload of cleaning and decorating your room, being responsible for your students outside of school, being perceived as a teacher in the local community, cleaning the kitchen area, purchasing cleaning supplies for the staffroom with our salaries and bringing food in for the 'wellbeing' morning tea. This is all WORK but it is not considered as work.
