I'm fine with either time- or complexity-based estimates as long as they're treated as estimates. I've not worked at any software company that did. What are the consequences of missing an estimate (especially one I did not create)? If it's "stay late until it's done" (with no OT because you're legally "exempt"), that sucks. If it's "your career is penalized, the same as if you were incompetent at the task itself", that sucks. I'd rather go back to a low starting salary, and earn OT when my manager decides to keep me working late. The money isn't as important to me as aligning our goals.
