I don't think people are judging you for the funeral; although 6+ days is a long time, I can see it being reasonable if it's very much out of town...I know my grandma lives on the other side of the US, and I've thought about what would happen if she passed away. You figure in two days for travel (there and back) and then with visitation and the funeral, it could easily be 4-6 days.
Now, if you had a non-negotiable vacation planned and did not put in any time off for it, that is another matter entirely. I have zero tolerance for people who KNOW they're going to be away for something and don't put their time off in on time, or at all, and then whine about being scheduled to work and end up calling out or guilting others into taking their shifts. If you don't know how to use eHR, find someone and make them show you. There is NO excuse for not utilizing the tools that Target gives you to make yours and their life easier. Rant over.
Now, I wasn't directing that at you particularly; there might be circumstances that I don't know about, but if you didn't follow procedure for your vacation, there's not much you can expect in terms of sympathy or assistance from your management. Your best bet is to try and talk to every person you can find about taking your shifts.
