With just days to go before the All-Ireland football final, union leaders in Chicago have been signalling their support for Mayo's bid to stop Dublin from winning a sixth title on the trot.

The globally recognised catchphrase 'Mayo for Sam’ has been displayed on one of the city’s landmark buildings, by the Chicago Federation of Labor.

The Federation’s President, Bob Reiter, said the links between the Windy City and the windy west of Ireland had prompted officials to display the slogan on the Prudential building in recent days.

Using lights on different floors to spell out the message, ‘Mayo for Sam’ dominated the 41 storey building.

Mr Reiter said there was a very strong and vocal Irish contingent in the Chicago Labour movement and he pointed to a particular Mayo presence among heavy equipment operators working in the city.

The Federation is the umbrella organisation for 300 unions in the area, representing around half a million workers. 

The Prudential Plaza will be used to display other messages of support for the Mayo footballers in the coming days. 

Mr Reiter said many Mayo exiles who would traditionally travel home for the final had been limited in their travels by the Covid-19 pandemic.

He is in discussions with elected officials to see how best to mark a Mayo win in Chicago, should the team prevail over Dublin in Saturday’s decider.
