1. As a whole, TU just cannot do "simple". For example when investigating and bringing in new technologies, most efforts drown in (perceived) "requirements" before they even have a chance to play and get an understanding of its characteristics. Many decisions regarding the recommendations of these technologies are left up to folks with personal ambitions who have a bias. The as a result, most of these efforts languish, are late, always confused, with little coordination.
2. The company allows (especially newer) managers too much freedom and autonomy. This generally isn't a problem, but at TU while most Managers are "ok", there are pockets of absolutely horrible ones who lack the maturity to manage people or know how to motivate them in a positive way. If you get hired here and you sense things are not working out, or a little off? My suggestion is to move to another group ASAP, or leave the company.
3. FTO. TU changed from specific vacation days (19/year) to an "Unlimited" model. From what I saw, there was too much work to request vacation, unless it was done months in advance. When making requests on shorter notice, always drew the ire from my particular manager. (Another example of immaturity). When I started, I was allotted 19 days, but I think I only took 2 days by July. This isn't good.
