JOHANNESBURG - Numsa is negotiating with motor sector employers again in an attempt to avoid a strike.
The union is demanding a 12 percent increase and a one-year agreement for the sector.
It says the increase will help employees during these tough economic times.
Companies have not made a specific offer yet.
"These workers, some of them are earning little as R21 per hour, so this would be a meaningful increase for those employees," said Numsa's Phakamile Hlubi-Majola.
"We have to remember these are employees like everybody who are struggling with the cost of living.
"They must just put something on the table so we got something to work with."
