Pros
The company cares about the safety of its line workers and strives to improve safety within both the company and the industry. Quanta also pays well and offers good long term incentives.
Cons
The cons are related to the corporate office, specifically IT services. There's a lack of leadership here at the executive level, and so all sorts of behavior is tolerated from IT leaders. I've seen bullying, a manager openly disparaging their team, name calling, threats, etc. I've seen adults cry here. That said, there are some good leaders here, too. There's just no real oversight or accountability for the bad actors. So, for those interviewing, I wouldn't necessarily avoid Quanta, but I'd take a serious gut check of your potential manager, don't dismiss any red flags, and don't get hung up on the pay. Once hired, you'll be working under someone who has virtually no checks on their behavior, while you'll have very little recourse in return.
