Over the weekend, AT&T stores were closed in a number of cities — from San Francisco to Boston to D.C. — when 40,000 workers walked off the job on Friday after the company failed to reach an agreement with the Communications Workers of America union. (AT&T told Fortune the majority of stores stayed open.)
In Oregon, Sen. Jeff. Merkley joined the picket line with workers. In New York City, Mayor Bill DeBlasio signaled support on Twitter.
Why it matters: It's the first labor strike AT&T has faced since 2012. AT&T is the largest U.S. telecom company, and the only one with a major union presence in its wireless business — the fastest growing part of the company. As a result, AT&T is having to contend with the pressures of competing with nonunion rivals in the increasingly competitive wireless sector, a company spokesman told the NYT.
