I have a UNICORN of a job lined up
INTERNSHIP
Another option all separations have... Have you completed SFL-TAP (you don't have to but they discuss it in SFL-TAP)? The 6m internship/jobs program will allow you to work for up to 6 months from an employer that's willing to provide a memorandum saying they are interested in hiring you and want to provide training. (As an example SFL-TAP here at Ft. Bragg has a 6m Auto Body Repair training program with Caliber Collision, you apply get accepted from Caliber, commander approves, SFL-TAP does paperwork, your new place of duty is a Caliber for next 6 months).
Talk to SFL-TAP about what they need to approve or review, then, talk to your employer let them know COVID delayed your separation and ask if they will write a memo for you to be an intern to hold your job. They CANNOT pay you because you are are still on the Army's payrolls, but it does allow you to start working and not lose the position. Very few employers have issues with this because they basically get your work time and the Army pays your paycheck of that time, so win/win for them. Many also use it for on-boarding and initial training so you can start actual work soon as you are free.
If the new job is out of driving distance you'll need to request pTDY from your command after the internship is approved. The job can not pay any expenses while on active service, but they can legally "reimburse you for cost of living/housing" as a signing bonus or relocation bonus once you are separated.
SFL-TAP or a local VSO should be able to help you set up the program. If you are or were in SOF and injured and have Care Coalition support, they can coordinate this stuff too. Typically SFL-TAP only offers the programs they already established, but the regulation allows any internship, you just have to do the extra leg work of getting the employer to agree and write the memo, and get SFL-TAP to support if you don't have a VSO or Care Coalition doing it for you.
LEAVE
If you have some lazy person who refuses to work with you and just tosses up road-blocks on internship... It is completely legal for you to use your leave time for this purpose.
You would need commanders written permission to "moonlight" a second job (basically counseling saying it wont effect your duty requirements and no conflict of interest like working for a company you just approved a contract for). With commanders approval for 2nd job, just use your units local leave policy to burn you leave up. Cover your ass by having a counseling with your commander stating he know's you'll be working during that time, and you'll have some kind of health and welfare check in or some such (to cover his ass as well) by text. It'll make you transistor faster after PEB anyways since you wont have the leave to use as transition leave.
I did something similar, my commissioning program did not allow leave for the full 2 years, and i was required to report with 0 leave balance. My BDE policy was any leave over 29 days required BN CDR and over 45 required BDE Commander. My company commander approved 3x 29 day leave forms and 1x 7 day leave form, and I took 94 days off with just the CO's approval, came in to work for 1 duty day between each one, checked in with my CO and left again.
