Labour has accepted 81 applications for voluntary redundancy, HuffPost UK understands, after the party moved to axe staff in order to drastically cut costs.
In total, 99 staff volunteered to take a payout and leave, but some applications were rejected as their role was seen as crucial to the running of a restructured party machine.
Those accepting the offer of voluntary redundancy will receive three weeks pay for every year served.
Labour bosses are hoping to at least make at least 90 people redundant as a way to save millions of pounds.
Keir Starmer has been warned staff could take strike action if compulsory redundancies follow the voluntary process in order to make up the numbers.
Labour staff who are part of the Unite union voted 78% in favour of strike action, while 75% of GMB members said the same, if people are forcibly cut.
The party was due to meet trade union representatives on Friday to discuss fears of compulsory job losses.
Unite regional officer Matt Smith said: “Labour staff have worked tirelessly for the party and should not be made to pay the price for this reorganisation.
Some party emplwho accepted voluntary redundancy had been told their current role would not exist in the new party structure.
Staff were told in July that the financial situation was so bad the party had only one month’s worth of payroll in reserve.
The Labour Party has been approached for comment.
