Gabrielle Union’s America’s Got Talent departure is being investigated. In a statement on Monday, a spokesperson for SAG-AFTRA told ET: “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. 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.” “For certain matters, our investigation and enforcement needs to happen independently and we are prepared to handle this issue accordingly, as warranted,” the statement continued. “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.” SAG-AFTRA added that, “while we have taken steps to investigate this matter, we have nothing to report now.” The union’s statement came just one day after NBC and AGT’s production companies, Fremantle and Syco, told ET in a statement that they “remain committed to ensuring a respectful workplace for all employees and take very seriously any questions about workplace culture.” “We are working with Ms. Union through her representatives to hear more about her concerns, following which we will take whatever next steps may be appropriate,” the statement added. Union responded to the statement by sharing a list of what makes “a solid apology” on Twitter.
