Throughout my research, I found that most news sources agree that Verizon plans to cut about 15,000 jobs. These actions align with their initiative to reduce operating costs and maximize current profits before the market overtakes them.
The original article posted with the claim is from Yahoo! Finance, which was originally posted on GuruFocus. The article was written by Khac Phu Nguyen, for whom I found no information or credibility. The article basically summarized the data from the Wall Street Journal article.
I couldn't find any primary sources on this claim, since Verizon has declined to comment to any news outlets or journalists and has not released its own statements.
For secondary sources, I found an article from Reuters, which sources its information from "a person familiar with the matter." They could be keeping the interviewee's identity anonymous for many reasons, though it does slightly discredit the information.
Additionally, I found another secondary source from CNBC, similarly stating Verizon plans to cut more than 13,000 jobs. Something interesting was that they sourced their information from a note written by Dan Schulman (Verizon CEO) to Verizon employees, and this note was seen by Reuters. So, this article could be slightly biased to just copying what the Reuters article stated.
Overall, the claim that Verizon is planning cuts to its operating costs, including about 15,000 employees, is true. More information will likely be released in the future as Verizon repairs its reputation, possibly by offering a public statement.
