Glasgow officials believe the move would help spread expertise around schools as well as giving teachers "fresh perspectives".
The plan is linked to another proposal for "mid-career refreshment", which would be open to teachers who had at least 10 years' experience and are under 50 years of age. They would be released for four to eight weeks' unpaid leave of absence during May and June but would be expected to pursue activities of "potential renewal", such as university study or work placements, which will benefit their school and pupils.
Glasgow is also pledging to increase teacher staffing over a five-year period, but this improvement depends on pound;7 million being released from the city's closures programme for general reinvestment in schools.
The extra cash would create a total of 212 full-time posts at a cost of pound;4.5 million.
