The Dundee business went into administration on Thursday after weeks of speculation about its future.

The meeting, held at Unite’s Dundee offices at 110 Blackness Road, will take place at 5pm on Wednesday.

George Ramsay, Unite industrial officer, described the collapse of McGill as “devastating”.

He said: “Unite pledges to do all we can to assist around 60 workers across Scotland.

“Unite will hold a meeting to help members deal with legal issues.

“We have also contacted the Partnership Action for Continuing Employment and Skills Development Scotland as we have particular worries for apprentices.

“Unite will be ensuring that the workforce are fully aware of their rights, and that those who may have a legal case are assisted.”

Unite said it would help any workers to fill in forms for administrators.

A trade union solicitor will also be in attendance to give advice “in respect of potential claims for a protective awards for failure to consult on redundancies”.

Barry Stewart and George Lafferty of Leonard Curtis, who were appointed joint administrators, said some jobs have been rescued after the fire and security division of the company was successfully sold.

A buyer was found in SPG Fire & Security Ltd – a Galashiels-based firm which intends to continue operations and service the division’s customer base.
