Dupont has an "employee-first" attitude that permeates the corporation and dates from its early years when the manufacture of gunpowder proved to be so risky. The Dupont family owners recompensed families of injured/dead employees by providing housing and supporting them for the remainder of their life. Safety became paramount in all operations. The attitude remains today. Despite the recent indiscretions in the LaPorte, Texas plant, Dupont is probably the safest chemical company on the planet.
If Dupont culture dominates, then this will likely prove a Renaissance for Dow. OTOH should Dupont culture be subjugated, it will ruin the value of the merger and we will all lose a company (Dupont) that has been possibly the best-run, most forward-looking corporation that has existed.
