Can anyone please explain to me what the difference is between a 'Head of department' and a 'teacher in charge'? According to my contract I am the teacher in charge of a fairly big department (100+ students & manage 3 staff) for which i receive only the lower end of the middle TLR. I am also in charge of another small department which i run but no staff to line manage. I do exactly the same as all the other heads of departments. Attend all the same meetings as them, complete all the same responsibilities and duties. But why is my job title 'teacher in charge' instead of 'head of department' aside from the TLR? Because I know for certain the heads of department have the title and larger TLR even if some of those depts are smaller than mine.
