Pros
Many opportunities to travel regardless of your position or time in the company. For those who are mobile, the company values flexibility and will give many opportunities to quickly move up the corporate ladder from site to site. Talented and mobile employees can generally get moved to larger divisions where they can work alongside increasingly talented colleagues and enjoy increased success as they move up. In areas with few employers, Corning generally over compensates even without market pressure. Work/life culture is extremely good for a manufacturing company, where vacation is usually approved and management is flexible about time off.
Cons
Talent seems to get naturally concentrated throughout the divisions. The company's strongest assets get moved to the larger divisions, while the smaller ones are left with the rest. Loyalty to the company is generally valued, but on the scale of decades (many employees have been here 20 years+). Corning struggles to maintain competitive benefits and wages in urban areas, generally paying significantly lower than the market rate. A metric driven culture has produced management that is sycophantic and subservient.
