As per the original plan, I believe everyone should be moving to hubs by second half of 2025, regardless of space constraints.
I am envisioning letters may roll out anytime during June or July for the next set of folks in other non-hub cities.
Directors in non hubs are being let go already and given final dates for this year end. I am not sure what is the fate of Virtual employees and those locations that are business as usual at this time.
