The cited document (did all the downvoters also take their time and actually read the TDRs and papers in detail??? Or are they just ignorant sheep?) is a rare case of putting the facts on the ground down in a written and approved document, despite being taboo in an organisation touting "equal opportunities" and such policies.
No downvotes will change the situation I warn about above, quite to the contrary: may my previous comment serve as a warning to all non-westerners at CERN for the time being.
The moment one experiences the consequences of such discrimination, things get far more real than an absurd conclusion you are alluding to.
Would you think, that this evaluation scheme has any consequences to peer evaluation within the same group? [aside from the inherent bias, not even mentioning all the other loopholes with categorisations such as Scottish (read western) MC-EST/PhD etc.]
...inconvenient truth?
What makes it even worse, is that the worse comment is actually factual.
