Union members are meeting to discuss job losses at an agency which supports young people at work in Sheffield.
Last week, charity Sheffield Futures announced it was to make 95 of its 368 staff redundant.
Trade union Unison said the job losses were as a result of the £6.5m cuts Sheffield City Council agreed to make earlier this month.
Sheffield Futures said it was in the process of informing staff about the potential job losses.
In a statement, the charity said: "The full impact of the cuts to our services is yet to be finalised. We are working in consultation with staff and union representatives."
Unison said the cuts would affect about 25% of the workforce and subsequently affect young people most in need of public support.
It has called a meeting for members of Sheffield Futures.
It said that at this stage it could not rule out the possibility of industrial action.
A spokeswoman from Sheffield City Council previously confirmed that an annual grant Sheffield Futures receives from the council had been reduced.
