Hell hath no fury like casino workers scorned.

Atlantic City’s main casino workers union is bringing hell to the doorstep of billionaire investor Carl Icahn’s beleaguered Trump Taj Mahal casino by mounting a strike on Friday.

The Associated Press reported that members of Local 54 of the Unite-Here union will go on strike after it has failed to reach a deal with union negotiators. The union is calling for the reinstatement of the health insurance and pension benefits of casino workers that have been stripped off them nearly two years ago.

Close to 1,000 union workers will conduct a mass walk out in Taj Mahal to kick-off their protest action, according to the union.
