Scotland's largest arts and leisure spin-off is to launch a probe into the wrongful sacking of five managers implicated in an overtime scam in the build-up to the Commonwealth Games.

Glasgow Life said it would be seeking "independent advice" on the findings of the Employment Tribunal, which instructed the council-owned trust to pay its former employees in excess of £100,000.

The tribunal judgement accused Glasgow Life of running a biased investigation carried out by senior bosses who lacked credibility and reliability.

The move comes as the city council's deputy leader and chair of Glasgow Life faces demands to investigate the 'kangaroo court' which led to the sackings.

The SNP said Labour's Archie Graham had to speak out about the "state of employee relations under his watch" as chairman of the Glasgow Life, while unions have criticised the tens of thousands spent by the organisation defending its sackings.

The GMB has also written to Glasgow Life's chief executive, Dr Bridget McConnell, demanding politicians who sit on its board are also involved in disciplinary disputes.

Leader of the city's SNP group Susan Aitken stating: "This damning judgement on the way that disciplinary practices have been conducted at Glasgow Life should ring alarm bells throughout the council.

"There must an inquiry, at the top level of both Glasgow Life and the council, into how this happened. What does the depute leader of the council have to say about the state of employee relations under his watch as chair of the Glasgow Life board?"

GMB Scotland organiser Benny Rankin added: "Time and again we told have Glasgow Life that they cannot conduct dismissals through a 'kangaroo court' and as this tribunal has shown, their internal disciplinary procedures are not credible and deeply unjust.

"Their intransigence has not only cost people their careers and livelihoods but has also wasted hundreds of thousands of pounds of public money on legal fees in a time of increasing austerity, a likely six figure sum that would be better directed towards the sustainability of jobs and services across the city."

A spokesman for Glasgow Life, said: “There is a legal and procedural process in relation to the Tribunal’s findings and outstanding appeals which is being adhered to.

“With respect of the judgment, independent advice will be sought on the findings of the Tribunal. The results of this, including any lessons learned and any recommendations, will be considered by the Glasgow Life Board.”
