The labour court will on Thursday rule on whether the banking union Sasbo can go ahead with what could be the biggest banking strike in 99 years. Sasbo plans to hold nationwide protest action on Friday September 27. It says as many as 50 000 workers have indicated that they will take part in protest marches and picketing against recent retrenchments in the banking sector. A second strike led by the Congress of South African Trade Unions is planned for October 7. Business Unity South Africa has filed an urgent court application to interdict the strike.
