Yaumo.
Contradicting years of research on Human Factors, you suggest that roster and leave issues have no bearing on the number of incidents. Interesting reading indeed – can you fill us in a bit on your revolutionary theory please? You don't seem to understand the meaning of 'blame-free culture' either – it refers to ATC management (not) just automatically looking for somebody to blame, but being constructive about it.....see?
Anyway, enjoy your 3 days off!
