Layoffs in AT&-owned WarnerMedia are underway with “more than 1,000 and possibly in the thousands,” according to CNBC.

The network obtained a memo about the layoffs written by WarnerMedia CEO Jason Kilar in which he said:

“Starting today in North America, we will be sharing which jobs are being eliminated and which roles have changed. We are continuing to review proposed changes in other countries across our non-US businesses, the timing of which will vary according to local regulatory requirements.

“Nothing about this is easy. But please know, these reductions are not in any way a reflection of the quality of the team members impacted, nor their work.

“It is simply a function of the changes I believe we must make in order to best serve customers. For those impacted, we will be offering severance and healthcare packages, in addition to professional services and team member assistance programs.”

CNBC noted that a WarnerMedia spokesperson declined to comment on the exact number of job cuts.
