I think that he could justifiably say that IF teachers were held in higher esteem by schools, parents and wider society.
While bankers and management consultants were being sent lists of office furniture and computer equipment to set up their home office at their employer’s expense, teachers were expected to teach remotely on whatever they had at home, some doing it on a dodgy last generation tablet.
At the same time, pupils have limited respect for teachers and most parents less so.
Pay a senior teacher the same as a medical consultant and treat them with the same level of respect and then, maybe, ask them to risk their lives.
