That's a very reasonable and business-minded way to approach your employment. You have a very direct interest in the company's success: your paycheck, reputation, friends, etc. Being aware if the company is exploding is simple sanity.
What I'm saying is that it's not a bad idea to understand the health of your employer (commercially, competitively, and financially) and recognize when that health changes for better or worse. If I get up and ask 10 co-workers who our biggest competitors are, I can guarantee 5 of them couldn't answer that question. If I asked the winning 5 which ones were growing and could possibly eat our lunch, 4 of them would fail that test.
Have you ever been let go from a job after being told for months/years that everything was fine and the company was doing great? I have. Luckily, at the time, I had no substantial obligations such as raising a family. Now I do.
I learned from that point on to never be blindsided again. And it's worked well for me so far. And I'm not a paranoid person at all. I sleep pretty well, actually.
Obviously we don't all have the option to bail at any time and find other work, but if this is the kind of culture you're seeing as normal, I feel very sorry for you.
Anyone in this position should -- for their own good -- at least attempt to take a longer view and see if they have options that don't involve constantly sleuthing to narrow down your job's expiration date. Unless you actually like living like this... in which case, hey, it takes all kinds. ;)
