Public service unions are expected to announce if the new wage offer had been accepted which would end a national, and at times violent strike, that started 20 days ago.

"The provisional planning is that the announcement will take place at 4pm," said Independent Labour Caucus (ILC) chairman Chris Klopper.

Asked if it would be good news, he replied: "It would be news", but when pressed further, Klopper said: "Yes, I think it is [good news]."

Congress of SA Trade Unions (Cosatu) spokesman Patrick Craven said most of the public service trade unions had completed the balloting process, except for the SA Democratic Teachers Union (Sadtu).

Craven would not be drawn into commenting on the decision by the other unions.

He said Cosatu would confirm during the course of the morning whether it would be ready to make an announcement at 4pm.

The government last week revised its offer to a 7.5 percent salary increase and R800 housing allowances, while public servants embarked on strike action to demand 8.6 percent and a R1, 000 housing allowance.

During the past 20 days, since the strike started on August 18, several protestors were arrested for public violence.

Two non-striking nurses were attacked and seriously injured in the past week by their striking colleagues.

State hospitals were crippled with several news reports claiming patients had died as a direct result of the strike and soldiers had to be called in to work as doctors and nurses.

Schools were also affected; several provinces postponed preliminary matric exams as many non-striking teachers were intimidated to stay at home.
