When teachers go on strike, the impacted school board can obtain a court injunction to order teachers back to the school and teachers can lose pay for each day on strike. In many states, they can also be dismissed from their teaching positions for striking
I feel that dismissing a teacher for striking is unfair because the majority of these strikes are for improving their pay, working conditions, or benefits. There have been cases where the teachers are striking for the rights or interests of their students.
