impostor syndrome is a psychological pattern in which an individual doubts their skills, talents or accomplishments and has a persistent internalized fear of being exposed as a "fraud".
of course it's about alienation, not that they're lazy or inherently bad in some way:

I agree with @Good_Username. I'm in Grad school, but I also have a lot of experience in my field. I get asked questions all the time that I answer, and I think I have a good answer for them. I help make things, design, and develop content. But there's always a voice in the back of my head that anybody could come in and challenge my ideas, assumptions, and activities and I'd be left...speechless? In grad school, it is heartening to see theorists writing or advocating for the same things I agree with (meaning I'm in good company, I guess?); but when I write papers I feel like a big fraud sometimes. Like do I know this, do I truly agree with this? As you progress into certain fields that are based on knowledge, you can't escape a sense of uncertainty. At least with the way social sciences are measured statistically, you have to account for so much variability in things.
I know what you mean about half-assedly doing work, I do that all the time too; but I think that's just humans being exhausted or losing any interest in their jobs. Let's be real not every job is interesting or the person is not a good fit — hopefully under communism that would be very different.
