A day earlier, union leaders had described negotiations as "intense" and cautioned against thinking the strike would end quickly.
More than 20,000 workers in the Southeast have been on strike since midnight Friday as the CWA charged the huge company with bargaining in bad faith and engaging in unfair labor practices.
The union said it had filed a complaint with the National Labor Relations Board, arguing that AT&T, which has $170 billion a year in revenues, had sent negotiators who had no authority to forge a deal.
The CWA’s four-year contract with the company expired on August 3. Union members have said they are most concerned about rising healthcare costs as well as job security.
If a deal is reached, employees could return to work the next day, according to Beth Allen, a CWA spokeswoman. However, “the plan for returning to work is negotiated with the company.”
The strikers are primarily technicians and customer service representatives in nine states. About 4,000 of those workers are in Georgia.
Since the workers walked out, their jobs have been filled by managers and supervisors. Company officials said they would give priority to urgent repairs and maintenance and likely wouldn’t handle new installations during the strike.
