My daughter almost went there. Her original MOS was 35F (Military Intelligence Analyst). After completing basic at Fort Jackson, her clearance was held up. She was stuck there for several weeks doing daily chores like raking leaves, KP, washing the CO's car, etc.
Finally they asked her if she'd consider switching her MOS. They dangled a 42A (Human Resources Specialist), which she could start the next day. She jumped at the opportunity.
Her clearance came in the next day.
35F v. 42A - I understand wanting to get out of the scut work while awaiting the clearance but that’s a huge change in the nature/location of assignments. I hope it all worked out in the end for her.
