From what I can tell, he's claiming that CERN discriminates against non-Western people. His evidence is a budget report, where they estimate how much something will cost based on the amount of people involved. The calculation adjusts for where the people are located, and the cost is higher if they're in a Western country.
But there are Eastern European, CERN member states. Some from there work for CERN, in Switzerland.
Do not think, that value as in monetary value just stays in a spreadsheet cell at HR. The evaluation has consequences in all other evaluations, peer evaluations etc. It does contribute to the evaluation of contributions etc.
