Unless the ERR MOU changes, N90 is the only facility that is a borderline death sentence. They'll simply never have the staffing to be able to transfer out.
Per Article 99, Section 6 of the slate book, hardships can be "approved", but denied due to staffing.
"If the Agency determines that the request cannot be accommodated due to staffing, the
request will remain active for fifteen (15) months and reviewed every six
(6) months by the Parties at the Service Area/AFSIAG level. After each
six (6) month review, a notice will be sent to the employee regarding the
disposition of the request."
@DankVectorz can verify, but I would assume hardships out of N90 would be "denied" due to staffing.
If you pass TETRA and if you certify at N90 (not to sugarcoat it, but for an OTS hire or CTI graduate with no experience, your chance of success is in the neighborhood of 1-3%), here are your options to escape N90...
1) DOD transfer. You apply to DOD jobs, when selected, you'd quit the FAA. After 6 months, you can apply to prior experience bids or apply directly to other facilities via CPC reinstatement.
2) See 1.
