Pros
UPS is a long established company, with a household name, a huge infrastructure and history of financial liquidity that's weathered several economic storms. They're company literature and mission statement boast many admirable principles with regard to ingenuity, integrity and managing people.
Cons
Over the past decade UPS seems to have abandoned the principles written in their own mission statement. While the PR department and boasts about new technology and innovation. In matters of practical Supply Chain operations they've stagnated. Recent attempts to pursue new technology has be self sabotaged by lack of foresight and tight purse-strings. Quality of service has also suffered by cutting loose experienced knowledgeable personnel in favor of younger people who will take the job for less money. Unfortunately, the very people needed to train the next generation have already been let go before their knowledge can be passed on. Work load for those that remain are doubled or even tripled as a result. The lack of work life balance results in even more labor churn.
