Tight labour market is true. But we cannot expect to have our cake and eat it. If we are short of teachers, we cannot expect to do more and more and more every year while maintaining or increasing standards. We have to right-size education based on staffing constraints. If the Education Service is 30k strong we cannot behave as if we are 50k strong. Then you get teachers working 80-90 hours per week including take-home work. It's ridiculous.
