Birmingham City Council has been accused of putting all of its 26,000 non-schools workers under threat of redundancy.
The West Midlands branch of trade union Unison said the local authority sent letters to the workers last week advising them of possible changes to their terms of employment.
Roger McKenzie, Unison’s West Midlands regional secretary, said the letters warned that if staff did not accept the new terms of condition they could be sacked.
Mr McKenzie described it as a ‘draconian, ill-considered, dangerous and politically motivated attack on council workers’.
He also called for the council’s chief executive, Stephen Hughes, to resign over the issue, adding that his position was ‘untenable’.
‘Unison is incorrectly stating that the entire council’s non-schools workforce has been put under threat of redundancy,’ said a Birmingham City Council spokesman.
‘The section 188 notice issued last week was the start of a consultation over possible changes to the terms and conditions under which staff are employed. This section 188 notice will not result in anyone being made redundant.’
