The Labor Union is the second solo studio album by American underground rapper King Syze.

Production was handled by Team 707, MTK, Skammadix, DJ Waxwork, Ill Bill, Sake, Sicknature, Tut the Instrumentalist and Undefined, with Chuck Wilson and Vinnie Paz serving as executive producers.

It features guest appearances from several Army of the Pharaohs members and Ill Bill.

The album was known for "[Syze] lacing his relentless, rapid-fire flow over a slew of spine-tingling gutter tracks".

AllMusic's Matt Rinaldi called it an "underground classic".
