Lindsay Lohan Exhaustion Claim Prompts Union Investigation

Two Hollywood unions are scrutinizing worker safety and welfare on Lifetime's Liz & Dick movie set following Lindsay Lohan's exhaustion incident last week.

Lindsay reportedly passed out so hard after four marathon days that a doctor found her unresponsive and called 911; paramedics found her to be just fine.

Lohan later joked about exhaustion and cute paramedics on Twitter, but two unions aren't laughing. Rather, they're concerned about workplace safety.

Larry A. Thompson, producer of the Lifetime movie starring Lohan as Elizabeth Taylor, said Wednesday that no violations were found in one union’s review.

The Screen Actors Guild-American Federation of TV and Radio Artists confirmed it visited the production and “will continue to visit” to enforce guild rules.

“We spoke with representatives from the production company, and they are fully aware of their contractual obligations,” the guild said in a statement.

"We will ensure that all applicable penalties will be paid."

IATSE, the stage employees union, said it’s keeping a watchful eye on the production’s working conditions following Lohan's four-day, 85-hour claim.

“We have had union representatives on the set since last Friday and will continue to monitor the hours and working conditions there,” the group said.

Filming has been rocky for Lohan thus far, to the surprise of no one. The star also was involved in serious car crash on her way to the set on June 8.
