I don't know what I'm gonna do. They knew about it. I think my recruiter just may not have recorded it or something. I have to find out.
Just take a moment to breath. Things sometimes get lost in the shuffle, and so long as you've been forthcoming so far, you hopefully should be okay. If you are able to completely cover the tattoo with a long sleeve shirt (available at costuming centers, ask costuming for specific colors that match your costume), then you shouldn't have any issues. Other than that, as you've probably already heard, QSR doesn't allow you to cover up tattoos with makeup... if you can't conceal with the tattoo with a long sleeve, you have a couple options:
Visit the Program Support Manager: I just checked some things, and it looks like the Program Support Manager will be out of the office until Monday. What you want to do as soon as possible is to visit her (Kelly Prezioso) - her office is to the left side of Clubroom Thirteen501 at Vista Way. She will be able to help you tide the waters and figure out the next step. To call, it's extension 1354 within housing or 407-827-1354 outside of housing.
Contact Housing's Program Office: If you are unable to wait that long, contact housing's program office at 7721 inside housing, or 407-827-7721 outside housing. You can also visit them (without an appointment) by visiting their office on the second floor of The Commons. They should be able to help, but the amount they are able to do may be limited (the Program Support Manager is the best route).
Visit your area's Cast Service Manager: You can also visit the Cast Service Manager area in your area, I believe at Epcot, they're all in a central office within the Cast Service building (they're in the blue section with the large Spaceship Earth mural, with a Golden Yellow "Cast Service" faceplate near the door).
The roles that you should be able participate in from what I can tell are Merchandise, Character Performer (past audition required), Full Service Food and Beverage, Hospitality and Vacation Planner. All require the use of stage makeup appropriate to your skin tone (like Dermablend) to conceal the tattoo.
