I hope this message finds you well, present circumstances excluded. This is a tough issue that really only has two directions or ways of approach. You can sign promissory note with the company to pay back the amount wtih interest. The second approach would be to take out a loan, if possible, and pay the loan back with your bonus. The second approach could possibly be handled by using your bonus as collateral if you can get your employer to sign off on a document recognizing your bonus or likely bonus.
Outside of those options, the only other mechanism is bankruptcy, which I advise against. It would be better to have wages garnished. They can only garnish a percentage of your check, not the entire check.
Just checking in on you to see if you had any additional questions. I want to make sure you are as comfortable as possible as you move forward. Thanks
