Cumbria County Council is still considering its response to a multi-million pound equal pay ruling.
Care assistants, home carers, kitchen supervisors and cleaning supervisors are among the workers who are set to receive “life-changing sums of money”.
The exact amount successful workers can claim will be decided at a later date.
The ruling follows a 10-week tribunal held in Carlisle between September and November last year. In total, 2,960 female council workers made a claim, 1,466 of them through the GMB union.
The union claimed that female workers had been unfairly excluded from a bonus pay scheme routinely paid to male workers. They also alleged that women were excluded from any extra overtime pay for working unsocial hours.
The union says of the 1,466 around 1,100 have been successful and will receive payouts.
A council spokesman said: “This is a complex judgment and it will take time to analyse the full implications.”
