Pay rises made to senior members of staff at Caerphilly County Borough Council were "unlawful on a number of grounds", according a report by the Wales Audit Office.
In December workers at the council staged a walkout after the Chief Executive was reportedly given a pay rise of around £27,000 in the September.
Caerphilly councillors will meet this evening to discuss whether to rescind a decision to award their top executives pay rises of up to £30,000.
Around 600 council staff staged a walk-out last month in protest having had their pay frozen for the past three years.
The meeting is due to start at 5pm.
Workers at Caerphilly council will stage a walkout on Monday over a decision to award a 27,000 thousand pound pay rise to the chief executive at the council.
It's angered local government workers as they say they've had their pay frozen for three years.
The council says the pay meets an independent external scheme and that it was presented to full council with no complaints at the time.
