Look the bank is downsizing all over the place. Given the bad PR, the bank willl NEVER say anything about layoffs and everyone let go will be under gag orders to not divulge anything without risking their severance. Over the next 18 months, about 10% of the entire staff will be let go and that assumes revenue growth continues. If there's a drop in revenue then that percentage will go up to offset lower revenue.
If you are worried that your department may be downsized or you let go, then it's time to update your resume and get searching for a job now or call a headhunter. Don't wait to get called into a last minute meeting because after that, everyone in your department will be looking for jobs. Don't let this bank's problems control you. Take charge and get out of the day 2 day fear of job losses.
