Retirement tax questions

Not sure how I prove that I had financial hardships though. I was on cohorts with 2 weeks off and 2 week on for about 4 months and that effected my sales performance and money that was supposed to be earned for me at the end of the quarter, even though I did get paid for the time off for the 2 weeks, I am not sure how that would work or if they would require any proof of hardship.
