Choose the best option / path of action to resolve this case with the Relationship lens in mind.

Go to the salesperson so I can point out the discrepancies and give the opportunity for them to provide the necessary documentation

Go to my supervisor with the information that I have because my role is to keep my supervisor informed so that he can do his job in an appropriate fashion.

Go to my supervisor with the information that I have in order to determine whether an exception was made for the top salesperson or some other reason exists for the receipts not being attached.

Don't go to my supervisor because the top salesperson deserves some freedom in his expense reports.

The case material is followed

You are a newly-hired accountant working in the Finance department, and you have just received your CPA license. Finding this job was difficult, but you finally have an in-house job with everything on your wish list for your ideal position. As you audit some expense reports and bills you discover a pattern that appears to have been going on for over a year. One of the top salespeople has been submitting over-stated expenses reports. The discrepancies average about $200 per month and have been as high as $400 per month. During on-boarding, you were told about the companys strict policy that requires receipts for reimbursement, but you also know that the IRS does not require receipts for expenses less than $25, a threshold which none of the missing receipts exceed.

You just read an article about a high-profile whistle-blowing case where an employee reported her suspicions that her boss was possible engaged in insider trading. This person faced four months of interrogation from various departments within the company, was outed to her boss as a snitch and when asked about an internal transfer was told she could find a transfer within the company by herself or simply find another job. You also remember from your university law classes that whistle-blowers are not protected as much as one would think.

The question is: What criteria are you going to use as you determine your path of action which can range from doing nothing, to going to your supervisor, or making an anonymous report to the company hot-line.
