This is not just happening in NM but in other states as well. It'd be nice to trace this idea and its spreading back to its source. You can find it on a search engine by searching New Mexico + teacher +sick time and refining your search to within the last month. I have read elsewhere that a teacher that incurs over 90 days sick time can be penalized if they use 3 of it according to the new policy. It is also happening in neighboring states as well.
