Taking the time to be safe is extra effort. Besides, the risk of something bad happening is small, and if it's not, it won't happen to me anyway.
Also productivity bonuses incentivize being unsafe. Safe time by being unsafe. And worse- when management (supervisors) don't see the risks or safety holes.
Every field, not just IT. Office politics combined with being outgoing and well spoken and suddenly they make >$150k but have no skills to show for it. Their management style lacks and is mostly based on discipline so they can say "I did something about this small mistake" and they don't know the basics but get away with it.
It looks so beautiful and peaceful there!
