Vantaggi
The people at TU are the reason it is so hard for most employees to move on to new adventures. For the most part, it is a group of people you find yourself actually happy to be around and having this sort of environment quite often makes it not feel like work. As well, the work environment is laid back and while you do sometimes find days or weeks or rarely months where you're working 14 hour days, the majority of the time you are able to take your time and really understand the technology you're working with and choose the best path to tread on each project. One last note is that for those willing to take it upon themselves, there is almost always room to grow, change, and move forward within the company. It may not always be easy, but it is certainly a place where there is something for everyone who wants to learn their chosen skills well and have the personal initiative to keep themselves moving forward on the path.
Svantaggi
Upper management, while being good people who are there for us, are quite often viewed as leading us down an ill path. It's not so much that people view them as not having our best intentions at heart - they do; it's simply the fruitless goals and the number of attempts at creating solutions for problems which don't necessarily exist. A less often taken view, but probably the more correct one, is that in reality the poorly decided initiatives are pressure from the behemoth of TU Corporate upper management that push their ideas onto what employees at the subsidiaries think of as "our" upper management.
