It would be misleading to refer to this as "layoffs."
Most affected CWA-represented employees, including affected employees in the Midwest and Southwest, have a job-offer guarantee that ensures they'll be offered another job with the company—only those who volunteer to leave or decline a job offer will leave the company.
In the Southeast, affected employees can choose to participate in our Job Bank Program for up to a year, during which time they receive a severance payment; continue to receive benefits and accrue credit for their pension; and can receive priority consideration and relocation benefits (if applicable) for other job opportunities as a regular employee.
