That’s maybe how business worked in the Victorian age, but not in the 21st century..
Every person at every level makes mistakes except 2 categories, liars and folk who do nothing.
If a culture is bred where a mistake gets you booted, then mistakes are hidden, decisions never taken and you can’t keep staff or attract staff. Plus company basically stops as no one will make that call due to it potentially being their last.
The encouragement to learn from mistakes and be open about them is written into the guiding policies for most businesses within their 9001/9100 systems, HR and ethical protocols.
In all the businesses I deal with I have never seen a culture of make a mistake and be fired, continually make them yes, break cardinal rules yes, but not have a culture where folk are terrified to make a decision in case it’s wrong then they are gone.
And as an ex Shop Steward the movement would never had allowed that to exist either.
