Barron's is planning to announce lay-offs next week, editor Ed Finn wrote in an email that he accidentally sent to the entire Wall Street Journal newsroom on Friday.

On Friday morning, Journal editor Gerard Baker emailed Journal employees to announce a round of newsroom buy-outs.

Finn — the president and editor of Barron's, which is owned by Journal parent company Dow Jones — apparently meant to forward Baker's email to Dow Jones Media Group publisher Almar Latour and two other company executives, in order to discuss what impact the Journal buy-outs might have on forthcoming layoffs (which had not yet been publicly announced) at Barron's.

"The email Gerry Baker just sent about wsj buyouts says that dj is offering 1.5x the standard buyout package," Finn wrote in the email. "Are we planning to go to the employees we are laying off at Barron's next week and offer them 1x the standard package. That could create some problems. Please advise."

But instead of clicking "forward," he accidentally clicked "reply-all," inadvertently sending the email to the Journal's newsroom.

"That was not intentional. it was a mistake. we had not been told what package was being offered to the several barron's folks who would be laid off next week," Finn told POLITICO in an email.
