Gil Schwartz, CBS’ chief communications officer for 22 years, announced Thursday that he will leave the company on Nov. 1.

Schwartz, who has a second career as a humor writer under the nom de plume Stanley Bing, broke the news in a memo to staff, reminding them that his option to exit CBS over the summer went unexercised.

“Given the exigencies of corporate life at that juncture, I elected to stay in place,” he wrote.

At the time, CBS was in full battle mode against its parent company, National Amusements Inc. — a conflict unresolved until the forced resignation of CEO Leslie Moonves on Sept. 9.

“Now seems like a much more appropriate time to move on,” said Schwartz, whose tenure at CBS overlapped with Moonves’ reign.

Moonlighting as Bing, Schwartz cut his teeth as an Esquire columnist, then chronicled the inanity of corporate life for Fortune between 1995 and 2016.

Schwartz also wrote books, the tone of which is captured in their titles: “What Would Machiavelli Do?: The Ends Justify the Meanness” and “Sun Tzu Was a Sissy,” to name a couple.
