The offer includes a three-year salary agreement, the union said.
"The offer comprises salary increases of eight percent to 10 percent in year one, 7.5 percent to 10 percent in year two and seven percent to 10 percent in year three," Solidarity spokesperson Marius Croucamp said in a statement.
In terms of the proposal, section 37 of the Metal and Engineering Industries Bargaining Council collective agreement would remain in place, with a provision that existing company-level agreements stay in force.
According to Seifsa: "Section 37 protects employers from having to engage in substantive negotiations at plant level, once a deal has been concluded on wages and related conditions of employment at national level".
The majority union
in the sector, the National Union of Metalworkers of SA (Numsa), confirmed acceptance of the offer.
Over 200 000 Numsa members in the
metal and engineering sector downed tools on July 1, demanding a salary
increase of 12%, down from their pre-strike demand of 15%..
They also demanded a R1 000 housing allowance, and a total ban on labour brokers.
The union announced on July 13, that it had lowered its wage demand to 10%.
