if we have one more day added to the weekends for us or what do you think?

I think it could work, but this is because I have a different approach, more towards the part of completed objectives and not hours worked. People who have more time to dedicate themselves to what they like end up being more efficient and productive in whatever they do.

Regarding your work, I have been a computer science teacher for an entire school year, and I attest to all the enormous planning work that must be done to organize the classes, the exams and the topics to be discussed, here in this country (Venezuela) the teachers They must follow an established order in terms of the topics and knowledge delivered, then it is mandatory that we comply with those requirements because it is required by law. Normally teachers invest almost 50% of their time in planning their classes, and I think this is something that should be improved to have more time that will allow them to research and better prepare to teach.
