Thirteen U.S. senators sent a letter to Santander Holdings USA CEO Scott Powell urging him to remain neutral instead of opposing efforts by the Communications Workers of America to unionize the bank's employees.
Santander has $23 billion in assets in Pennsylvania and New Jersey accounts and operates about 300 branches in the two states. As of December, 2015, Santander employed 17,511 in the U.S, according to its website.
Senators Cory Booker and Robert Menendez, both Democrats from New Jersey, joined Senator Bob Casey, a Democrat from Pennsylvania, and Sen. Elizabeth Warren, a Democrat from Massachusetts, in signing the March 27 letter.
