Two acting labor groups are investigating Lindsay Lohan's collapse incident

After Lindsay Lohan collapsed last friday because of exhaustion, two acting labor groups are investigating this matter. IATSE division director Mike Miller says, "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 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." Source
