Think small department- head of department and one other subject teacher. Subject teacher has made good impression in the two years he has been there, works hard, hits deadlines, excellent relationship with students, excellent results, taken on a lot of the head of dept role (writing schemes of work, creating resources, marking exam papers for head of dept etc) outstanding reports from ECT mentor and verbal feedback from colleagues, students and parents.
Professional working relationship between the two, but teacher feels that head of dept not particularly appreciative of his efforts and often takes credit for their work.
Head of dept secures new job elsewhere.
Tells teacher this news a week after securing job as a drop in comment during a meeting. Teacher congratulates head of dept and excitedly asks if school will recruit for head of dept position (teacher would love to do this, and thinks they are more than capable)
Head of dept casually says that oh, it was advertised last week. Teacher expresses interest in applying. Head of dept vaguely mentions the closing date being very soon and changed subject. Teacher quickly applies that evening.
Regardless of your views, eg teacher not as good as they thought- does this seem off to you?
YABU- teacher obviously not worthy of applying
YANBU- weird not to even mention to the only other person in your dept?
