The latest Samsung Electronics executive to go to prison for one of a variety of crimes is Lee Sang-hoon, chairman of the company’s board. A recent investigation unearthed conclusive evidence that Lee conspired with others at the Samsung to crush unions and unionizing efforts there, in violation of South Korea’s labor laws.

The investigation in question began back in 2013 with the leak of company documents describing methods for combating employee unionization efforts. It was the beginning of a years-long set of interconnected cases that would eventually lead to indictments and jail time for dozens of executives there.
