Everyone has a point of view here. The school principal (who does not want to be busy hiring staff during the year), the “single girl” who is likely using the job as a placeholder until she gets married and can move with her husband to Lakewood and the parents who wish some semblance of a routine in the classroom for their kids. Each sides perspective probably changes depending on where in the school year we are, how old the students are and the relationship between the teacher and school.
Looking at this from a different angle, I know girls who would drop someone who they felt would encourage them to renege on a committment and I know guys would would stop seeing a girl who would do the same. it says something about a persons character that they would do something like that.
