Pros
Good work/life balance. 40 hour work weeks are the norm for most salaried positions. Flight benefits are nice as long as your travel plans are very flexible. Pockets of good talent.
Cons
Pay is lower compared to other companies for similar roles and experience. All about supply and demand. There are a lot of people that want to work for United, and are willing to do so at a lower pay rate, and United knows that. Flight benefits are considered a form of financial compensation, and also a reason for lower salaries. United operates on a very thin margin, with expenses much higher than competitors. So when numbers don't come in good, reductions in force occur much too frequently. Recent reductions seem to be targeted at their older workforce, so they are losing a lot of wisdom and business knowledge. The remaining 20-somethings have been promoted to management levels, but have no clue on how to manage people or a business.
