Staff at one of Scotland's biggest nightclubs have lodged a grievance over working conditions and health and safety issues.
Several workers at the Cathouse rock club in Glasgow city centre have signed a collective complaint listing 48 separate issues, according to the Unite union.
Cathouse owners Hold Fast Entertainment said the accusations made against them were "grossly inaccurate".
Hold Fast Entertainment said the allegations relating to working conditions were "in many cases historic and where problems were identified, were resolved immediately".
