You are right. Muh of what is done "behind the curtains" is not only unseen, it is unpaid.
Teachers were already in a dire situation financially; now when you add health issues, a total lack of health infrastructure; technology issues and a considerable lack of tech resources and services, we have a very complicated scenario.
Much to learn and improve but few incentives to do it.
Students' motivation have also been seriously affected. Distant learning is not going to yield a good harvest.
