In Europe, this is very common to overwork. I am french and everybody that did not stay after 5pm was considered as "underperforming" and blamed for it. In the USA (at least after working in 3 companies in different states), if you stay after 5pm, it means you might not be able to complete your job in the allocated time and therefore, might be "underperforming". This is a simplification but this is the overall sentiment I have from both sides of the Atlantic.
