Treasurer Rob Lucas has taken aim at “greedy union bosses” in response to train drivers seeking a 4 per cent pay rise in each of the next four years.

The union representing Adelaide’s train drivers, The Rail, Tram and Bus Union has also sought approval from the Fair Work Commission to strike.

Rob Lucas says that the pay demand, which would cost the state around $190m if it went ahead, was tone deaf in the current COVID-19 economic climate.

Around 368 workers would be affected by the changes, if approved.

The news comes as the State Government moves to privatise Adelaide’s rail services next year.

The Treasurer says that the demands being made would mean hand the top paid train drivers a base salary of over $160,000 plus overtime.

If industrial action goes ahead, it would likely take place in the middle of next month and could affect train services.
