The union-sponsored rally will take place between 11.30am and 1pm in solidarity with action taking place across the globe. All council employees have been told of the strike and a short blast of the town hall fire alarm will be sounded at noon - in unison with other local authorities - to acknowledge the day of action. Barnsley Trades Union Council secretary George Arthur welcomed the council move.
He said: “I am pleased the council has decided to show solidarity. It is important that those who can influence the causes of pollution come on board.
“We are expecting a really good turnout from town centre workplaces and students from the college.”
Speakers will include local MP Stephanie Peacock, cabinet member for Barnsley Council Coun Chris Lamb, and a representative from Extinction Rebellion.
