Actually the do get a huuuuge cut in pay. First you reassign them to tolietry duty then you eliminate the yearly lavish secret performance bonuses.
I suspect that is what most of them are really upset about. The secret bonuses these rats were receiving. IIRC they were in the 20-50k sums.
I would like to hear more about these thieves and their performance bonuses. Follow the money, as in these useless eaters at State despise Donald Trump. But the real reason they are squealing like stuck pigs is no more secret performance bonuses and no more yearly automatic climbing up the GS pay scale.
