I noticed layoffs at Goldman Sachs Jersey City and NYC happening past several weeks with several senior people layoff, including those with decades of almost lifelong career with GS. If you want to save your job, you may be offered to go to Salt Lake City at the lower "cost of living" salary.
If you want to keep your salary, better find a job while you have one! From what I saw, it definitely has nothing to do with performance!
For new joiners from university I think we are safe since they invest in getting ideas from younger generations and we are paid less.
