230LLohanTaylor061312_001_X17.jpgLabor organizations, International Alliance of Theatrical Stage Employees (IATSE) and SAG-AFTRA, are launching an investigation against Lindsay Lohan's Elizabeth Taylor biopic Liz & Dick, after the actress and crew complained of exhaustion.

IATSE division director of motion picture and television, Mike Miller, said on Wednesday:

    “The IATSE is on top of the situation on the set of Lifetime’s ‘Liz and Dick.’ We have had union representatives on the set since last Friday [June 15] and will continue to monitor the hours and working conditions there. We take very seriously the safety and wellbeing of our crews, and are dedicated to seeing that they are protected from hazardous working conditions.”

SAG-AFTRA have also launched their own investigation into conditions on the Liz Taylor biopic, and say that "applicable penalties" will be applied if violations are found.

A SAG-AFTRA spokeswoman also said in a statement: "We have thoroughly investigated this matter and our business representatives have visited, and will continue to visit, the set of 'Liz & Dick," adding, "We have spoken with representatives from the company and they are fully aware of their contractual obligations. We will ensure that all applicable penalties will be paid."

Lohan first sparked reports of being overworked on the set when paramedics were called to her hotel room last Friday, after she was found unresponsive.

Lohan's publicist, mom Dina and the actress herself citied her "grueling schedule" for her exhaustion and the fact that she's been working "85-hour weeks." The following day, two crew members also reportedly had to abandon production due to exhaustion.
