The National Labor Relations Board (NLRB) has filed charges against Amazon, alleging that the e-commerce giant has illegally refused to bargain with a union representing drivers who are frustrated by what they claim are low wages and dangerous working conditions.

A U.S. appeals court has temporarily blocked the National Labor Relations Board from deciding whether Amazon.com must bargain with a union representing workers at a New York City warehouse, the first in the company's history.

WinCo has challenged the union election's fairness and legitimacy. Organizers say they believe it's a "stall tactic."

A federal labor board official issued a complaint against Apple Inc., accusing the iPhone maker of requiring employees to abide by overzealous non-disclosure, social media, and non-compete policies.

The National Labor Relations Board in the complaint announced late on Monday claims Apple required employees nationwide to sign illegal confidentiality, non-disclosure, and non-compete agreements and imposed overly broad misconduct and social media policies.
