Workloads and safety risks hit teachers the hardest in COVID-19: study

Since returning to the classroom it has become even harder to stimulate learning, students either consciously or subconsciously, are resistant to doing homework, and reluctant to answer questions in the classroom. In fact, the easiest way to quieten a classroom is to ask a question of the whole class, it is instant silence.
I am also coming across gaps in their learning, sometimes in unexpected areas, they may have covered it online, but none of it has stuck.
Pressure at school is unrelenting, we are expected to have a Google classroom entry for every lesson we teach and yet the first thing a student asks when they return to the classroom after being away is “what did we do?”
Setting assessment tasks and then having to reschedule because of absentees, it is constant and draining. Rather than have some consideration of these events and reducing meetings, they have increased.
I would go on but am getting depressed just writing this and I have multiple assessments to plan and correct.
How is everyone else traveling, I have taught for 30+ years and feel incredibly drained!
