Verizon CEO Dan Schulman released a public letter to the company's 100,000-person workforce on Thursday morning, revealing that more than 13,000 job cuts will begin today. The timing is optically displeasing, coming just one week before the Thanksgiving holiday.

"Today, we will begin reducing our workforce by more than 13,000 employees across the organization, and significantly reduce our outsourced and other outside labor expenses," Schulman wrote in the letter.

Schulman said Verizon established a $20 million Reskilling and Career Transition Fund for departing workers, focused on training, digital skills, and job placement in the era of artificial intelligence.

"This fund will focus on skill development, digital training and job placement to help our people take their next steps. Verizon is the first company to set up a fund to specifically focus on the opportunities and necessary skill sets as we enter the age of AI," the CEO noted.

Schulman's letter comes one week after the Wall Street Journal reported that Verizon was planning about 15% in job cuts, or about 15,000 workers.

Bloomberg's latest data suggests that 13,000 job cuts equal about 13% of its roughly 100,000-person workforce. WSJ notes this would be the largest workforce reduction on record for the carrier.

Also, last week, Verizon chairman Mark Bertolini told CNBC's Becky Quick on "Squawk Box" that the company needs to "do something different" as it undergoes its leadership change.

Separate but notable... 

So we guess that the "something different" is making 13,000 workers have a miserable holiday season.
