Gabrielle Union's sudden ousting from America's Got Talent has sparked a SAG-AFTRA investigation.
The Screen Actors Guild, the largest actors union, announced it would probe Union's axing from the NBC show where she served on the judge panel for season 14.
She allegedly complained about racially insensitive jokes and toxic environment before she was fired.
'We take issues of workplace health and safety very seriously. We immediately reached out to Ms. Union's representatives when these reports came to light,' the SAG-AFTRA told DailyMail.com in a statement.
'It is our practice to work closely with members who reach out to us and their representatives in instances like this, as that usually affords the best protection and best resolution for the affected member,' the statement added.

Time's Up shared a statement condemning NBC for enabling 'toxic' workplaces by 'protecting the careers of powerful men' last week after news broke about Union's firing
Time's Up shared this statement throwing their support behind Union. They referenced the string of allegations against Matt Lauer as one of the examples
'For certain matters, our investigation and enforcement needs to happen independently and we are prepared to handle this issue accordingly, as warranted. Our enforcement action is usually handled confidentially to protect the member involved, and we typically do not publicize these matters unless the member requests that we do so,' it added.
Union officials said the investigation has already begun but there is nothing to report just yet.
NBC also said they would launch an investigation into her firing, along with Simon Cowell's production companies Syco Entertainment and Fremantle, in a statement on Sunday.
The probe comes after women's advocacy group Time's Up condemned her firing, tweeting: 'Thank you #itsgrabrielleeu for speaking up for what's right.'
Time's Up called out NBCUniversal for enabling 'toxic workplaces' by 'protecting the careers of powerful men', while citing the Matt Lauer scandal.
'Now, Gabrielle Union was allegedly fired for speaking up about racist and inappropriate behavior she encountered working on NBC's America's Got Talent. Union reportedly endured and witnessed racially-insensitive comments and excessive criticism about her physical appearance, and it also appears she was punished for speaking out,' the Time's Up statement said.
'TIME'S UP applauds Union for her courage and once again calls on NBC to take these allegations seriously and take concrete steps to foster a safe and equitable workplace. Union's experience shows that NBCUniversal still has a lot of work to do to change its culture, so discrimination, harassment, and retaliation are no longer tolerated at the company,' it added.
Union allegedly complained severally racially insensitive incidents including one where guest judge Jay Leno made an anti-Korean slur on the show back in April.
On Sunday night Leno made his first public comments since Union's firing. He brushed over his racist joke and said: 'I love Gabrielle Union, she's a great girl. I really enjoyed working with her, she's really good'
The investigation was announced Monday, one day after Simon Cowell's company broke its silence on the firing scandal.
In a statement Fremantle and Syco said they were working with Union through her representatives to hear and address
