Pros
Frontier has many, many, many awesome employees with strong desires to work hard, be successful, and make the company successful. The employees want to improve the customer experience, they want to do a great job. There are leaders who really want to support their employees and improve the culture, but their hands are most often tied, and they are as frustrated as their employees.
Cons
Toxic culture, no vision or long term strategy, antiquated systems and even more antiquated thought processes. People who question status quo, or push too hard for change, are ostracized or let go. A strange "dictatorship" clique mentality exists in many of the leadership teams. A few really good leaders have been brought in, but it is doubtful they will be able to accomplish anything long term with the current schizophrenic environment.
