You need to change your attitude and not only look what the school needs to do from your perspective but also what a school expect from their employees and the children from their teacher.
How much effort would it have taken you to get written permission for your holiday which is very common practice.
You can't blame the school for a pandemic, a national and global emergency. You didn't show up for work anymore.
Name and shame? Don't worry about the forum rules, you will end up in jail for defamation. It will also bring attention to your own unprofessional attitude.
The school did nothing wrong; you did and where unlucky with the pandemic, national and global emergency.
Stop moaning and put negative energy in this topic and find a new job and learn from your mistakes.
