Birmingham City Council has begun the process of compulsory redundancies for a number of bin workers, the BBC understands, as the city continues to wrestle with the impact of strikes.
Unite union members in the city began a full walkout seven months ago, and in September voted to extend their action until March.
The local authority has unveiled plans to improve waste collection services, but the proposed changes to job grades include pay cuts of up to £8,000 for some staff.
The BBC has been told a small number of workers have this week been put on a notice period.
