Bosses at Bury council have appealed against an employment tribunal ruling which would have seen compensation given to around 1,400 female employees.
The workers took the council to an employment tribunal last month over claims they were not offered productivity bonuses in their jobs - positions traditionally held by women.
In comparison, they noted that male workers in equivalent areas, such as refuse collection, were eligible for such bonuses.
The council, which spent some £620,000 in legal costs fighting the case, has decided to appeal the tribunal's decision, which ruled in favour of the female workers and stated they should receive compensation to close the pay gap with their colleagues in professions such as gardening and refuse collection.
According to the government group, which represents a total of 17 wards, the men were not eligible for the bonuses based on their gender, but rather because of a genuine material factor, This is Lancashire reported.
The appeal is likely to take place in spring 2010, according to a spokesman.
