Amidst all the reorganization cr-p which has been going on for 3 years now, fidelity headcount has grown by ~5k.
With Boston seaport unable to accomplish current headcount and NC already at its peak, there is no way Fidelity can handle everyone back in the office, even alternate weeks with current headcount.
The reorganization and restructuring should be an indication of how Fidelity wants to g-n for organic attrition by saving themselves from paying severance.
And with recent push towards colocating and asking people to uproot their lives, it's yet another torture tactics.
