Continuation of Fringe Benefit Premiums. When a teacher is on medical leave of absence, following the termination of statutory sick leave, the Board will continue to provide its share of all benefit premiums during the period a teacher is in receipt of B.C.T.F. Salary Indemnity Plan short term benefits, and where necessary, a further period of one calendar year where the teacher is in receipt of B.C.T.F. long term benefits.
