If this is the case, it was filed November 23, 2015, which is not “just before.” His name is not mentioned, but this is the only one I could find.

He wrote the memo well before he filed the NLRB claim:
“The document is dated July, but it was leaked to journalists on Sunday (Aug 6) after more Googlers read the document and expressed their disgust on Twitter. CEO Sundar Pichai described Damore’s views as “offensive” and “not OK.”
During the interview, he said he wrote the memo to fill his time during a 12-hour work flight to China.”
Damore filed with the NLRB late Monday, August 7th.

“Damore told the New York Times he’d be seeking legal action against the company for terminating him. “I have a legal right to express my concerns about the terms and conditions of my working environment and to bring up potentially illegal behavior, which is what my document does,” he said. Later on Monday (Aug 7), he did just that, filing a complaint with the National Labor Relations Board.
