I agree with Flotsam7018. That's why we have designed by; checked by; and periodic reviews by a senior person to provide a sanity check. Hang in there and have faith in your ability. I empathize with your concerns about errors. I regularly see plans with things that are unbuildable or inefficient; things that will come back to haunt us later to some extent. I try my best to straighten things out.
I plan on being part of the "great resignation" with the next 10-12 months (hopefully that last tuition payment will be this year). I've been WFH since 3/17/20 although I have been going in to the office 1-2 days per week since last summer. WFH isn't for me; I like being around people. I'm not a number cruncher anymore. I'm more of the guy who runs the assembly line to keep the project moving. It's not the same dynamic WFH. Pre-pandemic, I would WFH occasionally; usually on a Friday or if the weather was very bad; I have a 2+ hour commute each way.
Over the years through mergers and acquisitions, I'm now with a very large firm. Pre-pandemic, I learned to ignore things like office politics, management restructurings, lack of leadership, and lately "woke culture". From being home, it's really the lack of leadership in the department over the past 2 years and lately not knowing where my next billable hour is coming from that lead to my decision to leave. I'm in a very large department, we have a new manager, who's being doing a great impersonation of the Invisible Man.
Another reason I want out. I worked with enough people who ended being "carried out" because they didn't know when to quit.
