The incident at Chula reflects a lack of understanding of leadership. Never expect someone to do something you will not do. To do otherwise is a perfect example of hypocrisy.
The teachers were not lying on the ground themselves. Why should they expect any different from the students? At university and college level, the teachers are employed by the students to serve them! Essentially the students are the paying customers — the attitude of false supremacy with staff expecting to rule over students as “less than equal” needs to go if education is to advance.
