LAS VEGAS could be paralysed by its first city-wide strike since 1984 next week after members of the Culinary and Bartenders unions voted by a 99 per cent margin to walk out.

Contracts covering 50,000 workers expire on June 1 and unions say negotiations with individual casino operators and hotels that started in February have failed to reach agreement. Those likely to participate include bartenders, room attendants, waiting staff, porters, cooks and kitchen workers.

Workers are calling for higher pay to take casino firms’ enormous profits into account — with companies expecting revenue boosts of between 10 and 30 per cent as a result of President Donald Trump’s massive tax cut for business, which slashed federal corporation tax from 35 to 21 per cent and abolished other taxes on the wealthy entirely.
