I've worked for two large corporations over the last 30 + years and both were baught out by other companies(large as well). Little changed after the transition although everyone was on pins & needles. The manufacturing process remained the same and the quality was never jepordized. Improvements were always being made as technologies were changing. If anything, the companies became globely stronger, better managed with a real vision, goals and a plan for the future. New products were always being developed and the capital for R&D, manufacturing equipment, education/training, maintenance upgrades, etc. became more available. Head count for operations, warehouse, lab, engineering, maintenance, accounting, purchacing, sales, materials management, have all increased even though only slightly.
