The requests seek disclosure of what each company's estimated gains from the tax revamp will be, how much they will spend on stock buybacks, how much capital investment they intend to make in the U.S. and abroad, and how many U.S. jobs they plan to create or bring back from other countries.

Request Rebuffed

American Airlines, AT&T, and PepsiCo. didn't immediately respond to requests for comment on Wednesday. One of the recent union requests has already been rebuffed. In a letter to CWA last month, Randall White, AT&T's Midwest labor relations vice president, wrote, “Because of the stated purpose for your inquiries, your requests are not relevant to the bargaining relationship between the company and the CWA.” White also told the union that it was seeking “irrelevant, immaterial” information.

Since passing their tax overhaul in December, Republicans have cited bonuses granted to employees at companies including Walmart Inc. and AT&T as evidence of the bill's broad benefits. “With 3.5 million Americans receiving bonuses or other benefits from their employers as a result of TAX CUTS, 2018 is off to a great start!” President Donald Trump tweeted on Feb. 2.

Democrats have countered that the legislation was skewed in favor of the wealthy, and any boosts to working class paychecks are “crumbs” compared with the billions in handouts to big corporations.

The unions' announcement of their push for corporate disclosure comes four weeks after Teamsters members at a Toyota Motor Corp. parts distribution center in Torrance, California, voted to authorize a strike, rejecting a contract offer they said was far too stingy in light of the company's recent earnings boost from the tax bill.

“We heard President Trump say that workers would be getting a pay raise with the tax breaks, so when Toyota got a $2.7 billion windfall, we expected to finally be able to catch up with the high cost of living in our communities,” employee Daniel Valenzuela said in a statement released by the union.

The workers, who service Toyota repair shops from Southern California to Salt Lake City, voted March 24 to reject a subsequent offer from the company, which they said included raises of 1.2 percent a year. On March 27, the local union's secretary-treasurer sent a letter to Toyota dealers warning that “the workers are on their way to your dealership in the very near future to handbill your customers with the media present to document the event.”

“We greatly value represented team members at our Los Angeles Parts Distribution Center and have offered them a contract that not only delivers considerable improvements over their current, industry-leading wage and benefits package, but also greatly exceeds comparable local wages and benefits,” Toyota spokesman Eric Booth said in an emailed statement. At a briefing last month in Tokyo, Toyota Senior Managing Officer Masayoshi Shirayanagi said that the legislation added about 290 billion yen to the company's bottom line.

Disney Unions

The tax bill has also become a flashpoint in negotiations between Walt Disney Co. and a coalition of unions representing theme park workers in California and Florida, which filed Labor Board complaints last month accusing the company of discriminating against union members who are currently in contract talks. By announcing special $1,000 tax-cut bonuses for employees but holding them “hostage” from those in negotiations, the company violated labor law, union leaders alleged.

In a statement last month, Disney said that for union members, the bonus would be part of overall contract negotiations. “We presented fair and compelling offers to unions on both coasts, and we hope they will reach timely agreements with us on behalf of their members,” the company said.

The Disney unions' allegation should be pursued by the NLRB, said William Gould, a professor emeritus at Stanford University who was chairman of the labor agency under President Bill Clinton. “The employer is allowed to engage in hard, tough—uncompromising at times—bargaining,” he said. “What's impermissible is to say that you only get the bonus if you agree to waive everything that's on the bargaining table—that makes the bargaining table useless.”
