Just 6 months after a companywide audit of worker IDs resulted in the loss of 269 of its 489 employees, Champion Window has decided to shut down its entire manufacturing division — axing an additional 135 workers. The largest manufacturer of vinyl and aluminum windows in the South Central U.S. was served with a grand jury subpoena last November over its hiring practices; a subsequent investigation by federal agents revealed that a large number of the company’s employees had no legal authorization to work in the U.S. Champion will shift its manufacturing operation from its Houston plant at 12427 Duncan Rd. near the Willowbrook Mall to its parent company, Dallas-based Atrium Windows and Doors, in December. Recently, Champion filed suit against 2 former top executives, alleging their “negligent disregard” for whether job applicants had authorization to work in the country “nearly crippled” the company’s operations.
