Pros
I came to L3Harris approximately three months ago from a larger engineering firm in the area. So far, I do not regret the transition. I was not unhappy at my last job, but L3H had a position that was more closely aligned with my personal interests. So far I have received a significant amount of training and support to help me in my new role. Things seem to work more smoothly here, and there is less red tape associated with gaining access to resources. If employees are not completely satisfied with their current position, we are regularly encouraged to seek out other opportunities within the company. I also believe there are less "filler" employees at L3H when compared to similar companies. Every person on my current project seem to be vital and are entrusted with important tasks, as well as knowledgeable duty experts. Management seems to listen to input from those with detailed expert knowledge and experience, which is a nice change for me personally. There are also a ton of positions and projects, so it's easy to find something you're really interested in.
Cons
COVID-19 has created some abstract barriers to team engagement. I understand L3H has an obligation to protect their employees, but there is a marked difference in the productivity of detailed problems when we try to solve issues via teleconference and emails, rather than in-person working groups.
