Pros
Former Raytheon employees have heart. They truly care about what they do and the Customer (war fighter/peace keeper - pick your position). You will learn a lot here about yourself, and how to work in teams (whether good or bad). Former UTC employees are consultants and used to working a contractor mindset (this is not a pro).
Cons
Since the merger with UTC, I have not heard one good, positive, enthusiastic comment from anyone; be it from the now consolidated 2 businesses (had 4 last year and 6 in 2012) or the corporate entities. The merger is a takeover. The skills, innovation, thought and insight of the former Raytheon employees has been brushed aside to be led by multiple consulting firms. Book expertise is what's changing this company. Real world application is now a thing of the past. Pooling resources instead of building skills. Disconnect and inconsistent messaging and communications to employees. 10% pay reduction for parts of the company and mass layoffs elsewhere, including Pratt and Rockwell. Change is good, yes, but this feels like the real life version of the movie Annihilation. Forecast for career advancement and truly building a skillset are slim. Compensation is taking a hit from "Covid". Work/Life balance is decent but only if you have a manager who believes in it (policy is one thing, but everything is manager discretion). Senior mgmt is self-absorbed and is well versed at lip service. There is a clear disconnect between what sr mgmt says and what we all experience day-to-day. Culture and values are changing and not necessarily for the better.
