Pros
Company is stable, well-known and revered in the market. Moving around (laterally) within the company is fairly easy. Getting every other Friday off and Christmas vacation is a plus.
Cons
Lack of diversity in leadership. Leadership often does not stand by employees. Completely disorganized. Constantly rolling out new company-wide initiatives that never pan out. Work-life balance isn't the greatest. Pay is low compared to market. Benefits package has declined. Lots of nepotism, favoritism, and lack of advancement for the hard-working. Talent is often overloaded with work while under-performers aren't reprimanded. HR works against employees, ethics board is a joke and retaliation is rampant when wrongdoing is reported. Constant layoffs. Advancement is nearly impossible. If you are forward-thinking, creative, and looking to grow, avoid Aeronautics all together. Nine times out of ten you will be doing work that does not correlate to your skills--or doing work that does nothing to grow or enhance your competences.
