Tesla Denies Claims That It Tried to Block Unionizing Effort

Detroit (AP) -- Tesla Inc. is denying claims that it threatened to fire pro-union workers at its Fremont, California, factory and tried to prevent them from passing out union literature.

The National Labor Relations Board filed a complaint against Tesla earlier this month, citing multiple incidents in which Tesla security guards allegedly refused to let off-duty employees hand out leaflets about the United Auto Workers union near the doors of the company's factory. Tesla workers further allege that they were prohibited from discussing worker safety concerns and were interrogated about union organizing efforts by Tesla human resources employees, according to the complaint.
