Operations at the SA Revenue Services (Sars) were back to normal on Monday while the revenue collector waited for word from unions on whether their offer would be accepted, a Sars spokesperson said.

"Everything is normal, it's fine," said Adrian Lackay.

There were further talks over the weekend on the pay dispute which was punctuated with strikes at the taxman's offices and disrupted traffic flow at border posts last week.

Manie de Clercq, deputy general manager of the Public Servants Association, confirmed their members were back at work and were considering a draft agreement.

Some clarifying amendments were being made to the deal, which could lead to increases of between nine to 11 percent being implemented if accepted.

The National Education, Health and Allied Workers' Union was not immediately available to comment.

The unions had hoped to secure a 12.8 percent increase.
