HOLLYWOOD, CA. (CNN) - Lindsay Lohan's complaint that working long hours caused her to collapse from exhaustion has triggered a union investigation. Producers called paramedics to the starlet's hotel room last week when she wasn't responding to knocks on the door.
Her publicist said she was just sleeping after working long hours. Later, Lohan tweeted that she had worked 85 hours in four days.
Now, the union is looking into working conditions on the set of "Liz and Dick". Lohan plays legendary actress Elizabeth Taylor in the Lifetime film. The set is being closely monitored by union representatives.
The movie's producers did not immediately respond to requests for comment.
