It happens much less in organizations where leadership set dates based on following basic scrum estimation and an earnest conversation rather than some manager throwing a dart at the calendar and using that random date as a lever against the teams driving artificial velocity. Other parts of the org like UX and product need to fulfill their obligations as well or it won't work. I've found a lot of teams deep into a death march who never bothered to push product on incomplete requirements.
