Feel free to correct the rudimentary assumptions I'm making.
Per the last 10-K, on 12/31/22 there were 238k employees with 19% offshore. Obviously the numbers are different now, but for transparency purposes, I will use these figures. That means there were 192,780 US employees and 45,220 I&P employees.
We know Charlie needs to bring down headcount and the goal is 30% of employees in India and the Philippines. So let's say the goal is 210k employees total. That means there would be 147,000 US employees and 63,000 I&P employees.
Total employee count decreases 28,000. This comes from reducing US headcount by 45,780 and increasing I&P headcount by 17,780.
Reducing US headcount by 45,780 is nearly 24% of the 192,780 US employees at the start of 2023. They want 1 of 4 US employees gone. This will come from a variety of sources - voluntary attrition, dismissal for cause, layoffs, etc. More will come from non-hub locations than hubs, presumably. But to reduce the employee count as Charlie has told investors will occur and to increase I&P's proportion of the employee base, that's how many US positions will not exist anymore. 1 in 4.
