I accepted the job last week with the initial information that my salary would be at the step 10. I am supposed to start work next week, and was notified by email about the local policy and salary change yesterday. Every example I could find on OPM shows the matching of pay being reverted to basic pay first, then adding locality pay after (this is from the OPM site):
"Voluntary Demotion from Lower Locality Rate to Higher Locality Rate
In 2005, a GS-0201-11, step 5, human resources specialist in the Washington,
DC, locality pay area ($59,464) voluntarily accepts a demotion
to a GS-0201-9 position in the San Francisco locality pay area. Since this
is a voluntarily demotion, grade and pay retention do not
apply. As provided by 5 CFR 531.215(b), if an employee's official worksite
after demotion is in a different geographic location where different pay
schedules apply, the agency must first convert the employee to the applicable
pay schedule(s) and rate(s) of basic pay in the new geographic area (San
Francisco locality pay area) based on the employee's position of record
before processing the demotion. The pay schedules applicable to the employee
in San Francisco are the General Schedule and the San Francisco locality
rate schedule. The GS-11, step 5, General Schedule rate is $51,271, and the
GS-11, step 5, San Francisco locality rate is $64,801. The agency decides
to use the maximum payable rate rule in 5 CFR 531.221. The employee's highest
previous rate (HPR) is the GS-11, step 5, rate on the General Schedule.
(As provided by 5 CFR 531.222(b), use the employee's underlying GS rate
as the HPR in applying the maximum payable rate rule in 5 CFR 531.221(b),
which is designed to use underlying GS rates to avoid the need for geographic
conversion.) Compare the HPR ($51,271) to the GS-9 rate range on the 2005
General Schedule. There is no step rate that equals or exceeds the HPR;
therefore, the maximum payable rate is the GS-9, step 10, rate ($48,604).
The agency may set the employee's GS rate at any rate in the GS-9 rate range."
Of course, the caveat is the very last statement. Does this mean I'm pretty much out of luck? Is this something I should mention to the hiring official? I could decline the job, but that would be like cutting my nose off to spite my face. I'm just worried that if, by some miracle, that I get selected for a position that was at my previous higher grade here, I would start back at step 1 instead of my previous step.
