Education is absolutely an essential service. Parents, students, teachers and administration experienced the impacts on the Education system through COVID 19 and students are suffering from the pressure to 'catch up.'

Having said that, if the intent of the question is to determine whether I believe that teachers should be enabled to strike, then I would suggest that any labour movement should be able to stand up for their rights as workers by the legal means provided to them. When work environments are not acceptable and pay increases don't maintain pace with the cost of living, there should be ways to enable workers to express their discontent.
