Vantaggi
Emerson plans fairly well, so it's stable (layoffs are rare and when they occur are smaller scale than other companies'). I've worked with many smart, hard-working people at Emerson and have had the chance to get to know several facets of the business, to interact with all levels of the organization, and to work with people all over the world.
Svantaggi
It can be hard to get things done because the structure of the business doesn't reflect/support how Emerson markets itself (goals don't mesh with the tools/culture to achieve them). Career development/advancement can be difficult if not an engineer or in Finance. "Duties otherwise assigned" often leads to people consistently doing work that's beyond the responsibility of their position, so they're not compensated for what they really do, and they end up behind the curve on the pay scale. Diversity is also a bit of a hole; if you look at a picture of the Emerson board, it's all middle-aged white guys.
