EAST Riding Council has issued a number of notices to staff whose posts are at risk of redundancy.
The 90-day notices are a formal warning that certain posts at the authority could be axed at the end of March.
The council has yet to reveal how many posts are involved.
But Syd Cunliffe, East Riding branch secretary of Unison, has revealed the posts under threat are in the early years and youth support services.
He said: "We have only just been informed of the proposals and we met with the managers from the early years and youth support services on Saturday morning.
"We know the council is looking to make £60m of cuts over the next four years and this is the start of that."
The union understands 22 posts are at risk but Mr Cunliffe hopes many of those can be saved.
He said: "There are proposals for three redundancies in the early years service but we hope that won't be necessary.
"But we are disappointed by plans to make 19 redundancies in the youth service.
"The department was only restructured last year when the Connexions service was integrated with it. We will be meeting staff this week to discuss the proposals. It is still very early days.
"Other unions will also be involved in these discussions.
"Children's services needs to make £4.5m savings in 2013-14 but we think most of these can be made with non-staffing overheads such as building maintenance.
"Our main concern is that frontline services are not affected by an cuts in staffing."
The Mail understands many are fixed-term positions which are only funded until the end of the financial year.
The council has made 47 people redundant since 2010.
In February, it announced another 170 posts could be scrapped over the next two years to help deliver savings.
This year the council is aiming to make £15.5m of savings as funding from central government continues to be reduced.
Council leader Councillor Stephen Parnaby has already pledged to avoid compulsory redundancies wherever possible.
Speaking about the expected deletion of the 170 posts, he said: "I emphasise that every effort will be made to redeploy and retrain those affected and I anticipate this figure being much lower in reality.
"There is no intention to issue global redundancy invitations and we remain confident this will not be needed."
In recent months, he has continued to draw comparisons with neighbouring Hull City Council, where about 1,000 staff left through voluntary redundancy early last year.
Another 240 back-office administrative posts are currently facing the axe as part of a savings drive.
