> Most companies try to extract the most value from their employees and this may mean overloading them

Exactly this. If managers notice that your team is doing everything on time, they will remove a member or two from your team, until you can barely meet the deadlines. Then they get a bonus for reducing the company costs.

It requires some experience to realize that it is not your fault if the deadlines are in danger. That is system working exactly as intended. But of course the company will pretend it's your fault. That is also system working exactly as intended. (In USA, this results in you doing a lot of overtime. That is also system working as intended. The urgent situation is not something unexpected; it happens every year in every project, it is a part of the plan.)
