I don't think so (though they didn't help). From Forbes:
Mather had been accused of inappropriate workplace conduct prior to this latest controversy. According to the Seattle Times, when Mather was a Mariners executive vice president in 2009 and 2010, Seattle attorney Robin Phillips brought complaints against Mather on behalf of two women who worked as executive assistants for the team. The Seattle Times reported that the cases were settled out of court.
Phillips also represents Lorena Martin, a former Mariners high performance director who filed a wrongful-termination lawsuit in 2018. Martin alleged she made complaints to Mather, minority owner Buck Ferguson and Stanton about a hostile work environment, but she was instead terminated from her position. The case was ultimately handled by an arbitrator, and the Seattle Times reported Monday that the case “was resolved,” according to Phillips. Martin declined comment.
