Rationale behind changes in WFA is to decrease retention of new employee, and reason of VSP is to increase retention, which (it was stated yesterday) is below market average. Kinda feels like Catch 22.
My understanding is - fire oldtimers cause they are more expensive, and hire newbies for lower salary (doesn't matter if it's offshoring, or new job market - even in Poland you can pay IT people much less than it was 2-3 years ago). And unfortunately US is the most expensive sites and there is no way around it and that's why you are taking most of the beating.
Anyways, I get the Titanic vibes. Iceberg ahead, but band is still playing. Better to grab something while we can.
