I worked in Global Payments in PGH. I can believe 25% of staffing meeting below expectations.
During my time there:
We recruited four associates with substance abuse problems. These addictions directly impacted their job performance and attendance.
40% of my department had learning disabilities. ADHD, Bi-Polar, Autism, or general re--rdation. Some were medicated, all were in therapy.
50% of the department did not know what they were doing any given day. This includes both VP Managers.
Department employing leadership with a lacking functional ability to communicate. One suffered from Autism the other suffered from being grossly under-qualified.
If my department was a core sample of BNY. Yes, this firm cannot recruit and 25% of the staff can be shown the door.
The problem is, if these under-performers are connected or have favors... they will still exist at the firm while "better employees" are shown the door.
With my previous department, the train-wreck staff members are still there while the disastrous leadership were moved to other positions within the bank.
