Talks will resume on Monday between Unite and Birmingham City Council.

The warning, which union Unite condemns as "disgraceful" comes after dispute talks broke down.

Staff at John Crane are planning to walk out for six days across April and May.

He says the decision was due to Unite's refusal to condemn threats of violence by those on strike.

Nadine Zubair says the strike day will be used to "celebrate staff".

Binman Steve Bissett is on strike in Birmingham, which is in its third week of all-out action.

But Unite the Union condemns Councillor Majid Mahmood's claims as "smears", as the strike grinds on.

More than 80% of balloted union members support striking as they fight to stop redundancies.
