METRO drivers could stop work again next Friday if meetings between the Rail, Tram and Bus Industry Union and management next week fail to resolve a pay dispute.
A stop-work action yesterday halted bus services statewide between 10am and 2pm.
Next week's action, if it goes ahead, will hit the high- traffic school pick-up time of 2pm to 5pm.
The drivers are demanding a pay rise of 3per cent a year for three years.
They have been offered 2per cent, up from the original offer of 1.5per cent.
Union president Sam Simonetis said the union hoped to meet with Metro management early next week.
