Its a little known secret that managers deliberately promote anxiety driven development because it keeps workers at "peak productivity". A couple of the major things i've seen companies do in the past over and over again to myself and to others I worked with:

1. Ambiguous or no deadlines, frequent check ins, "crunches" when their deliberately poor planning doens't work, keeping an air of uncertainty around everything.

2. Giving the same tasks to multiple groups and deliberately pitting them against one another in a kind of unhealthy competition. Constant fear of obsoletion.

3. Little or no positive feedback, only give feedback when things are wrong. Deliberately vague about future career prospects or growth, holding the carrot out but with no promise to deliver.

The problem is that each of these are tied into natural "sources" of anxiety that are likely to happen with or without the company actively promoting it, but the company promoting it can make people work even more frantically. The problem is they don't realize people produce their "best" work when they have creative freedom from anxiety.
