Johannesburg - Talks between SA Airways and the SA Transport and Allied Workers' Union were likely to continue on Tuesday afternoon, the union said.
Technical staff at SAA started striking on Monday.
"SAA technical management are very arrogant about the situation. They are not cooperative... the fact [that] they are not budging from the 6.5 [percent] offer is a clear indication of that," Satawu general secretary Zenzo Mahlangu said.
The latest offer tabled by SAA technical was a mockery and could not be regarded as a revised offer.
"...In fact the revised deal they were talking about was just a 0.1% increase. It is not even considered a revision as it is still not a substantial move from the CPI numbers... We might meet later today [Tuesday]."
Mahlangu said Satawu would be willing to accept an offer below their initial demand of 12%, but indicated a double-digit increase would be a fair compromise.
"SAA technical has made profits of about R161m, they share that money among themselves [the bosses], and don't consider the workers."
He said another union might join the strike from Wednesday, which would "create bigger delays than what have been seen".
"What SAA's public relations are telling you that there are no delays is just nonsense... This strike is causing massive impacts," he said.
Satawu spokesperson Vincent Masoga listed five flights that were affected by the strike.
"SA203 [to] New York was delayed for 29 minutes due to [a] manpower shortage, SA260 was delayed for 21 minutes for the same reason... SA280 [to] Perth was also delayed due to manpower... SA363 experienced a 32-minute delay, and SAA288 was delayed for five hours," Masoga said.
SAA could not be reached for comment.
