Striking South African Breweries (SAB) workers affiliated to the Food and Allied Workers' Union (Fawu) handed over a memorandum to their employer on Tuesday.
Fawu spokesperson Dominique Swartz said about 100 striking SAB workers gathered at the company's premises in Newlands, Cape Town.
"We are handing over a memorandum which states that we want a 9% increase," she said.
The employer was offering 7%, but Swartz said it worked out to workers receiving only 4.4% of that percentage.
The remaining 2.6% came in the form of performance-related payments.
"We just think that is scandalous," said Swartz.
SAB management received the memorandum from the workers.
Hundreds of Fawu members on strike
The Fawu strike began over a week ago.
The company said it had a contingency plan in place to minimise disruptions to operations and customers.
On Monday, SAB spokesperson Robyn Chalmers said a strike was always problematic, but that the company was confident of its plan.
"SAB has a total of about 6 400 people working in the beer division, of which about 2 800 are members of the bargaining unit," she said at the time.
"Currently, about 860 Fawu members are on strike, amounting to just over 30% of the bargaining unit – so a minority of workers are on strike." – Sapa
