I work for a government contractor as a third party independent contractor for about a month now. I directly report to and take orders from the government employee that I interviewed with before getting the job and he was glad that I took the offer.
This is somewhat of an odd situation, even though he is the customer (the government employee) I get treated as though I'm almost a new coworker to him. He says he appreciates my good work he has faith in me to get a project done. Keep in mind he is a Senior and I'm young (mid 20's male).
Here is the issue. I noticed that he likes to talk about somewhat borderline racist jokes that he looks up on the internet "AND" shows to other coworkers and contract workers(note other coworkers do not look these jokes up he shows them to them) . In no way does he try to say it in a low voice, and additionally goes to other coworkers/contractors offices to tell the joke there. I looked up these jokes, and notice that he leaves out the racist portion but says the rest of the joke. These jokes are directly aimed towards my ethnicity.
In the office I am the only person of this ethnicity, all of the other government employees and contractors are the same majority ethnicity.
I don't understand why he likes to tell these jokes and explicitly leaves out the ethnicity portion of the joke. He knew my ethnicity and what I looked like and met me in person before he hired me, and he is very polite and helpful when I ask him work related questions, but he still likes to make jokes targeted at only my ethnicity.
Are their any options I have to address this situation? How do I protect myself from blow-back while doing it?
