When I worked in public sector with a strong union, we didn't do crunch, we accepted that deadlines are malleable and my project managers always anticipated and resolved deadline problems before they became a problem.

Now I work for IBM, and I am expected to work late as much as it takes to ship on time. "On time" is of course completely arbitrary and determined by people who have no understanding of the technical tasks required to ship the project (and most pertinent, don't listen to me when I provide my expert opinion that the timeline is not viable). And they expect to not have to pay me for that overtime.

Not being able to exploit your workers encourages realistic deadlines.
