With the exception of Gloria from modern family, I have never seen anyone happy about getting a jury duty notice in the mail.
I can understand that. When I received my first summons, I was in between my junior and senior years in college and had just excepted a part-time job at a local cookwares store (which turned out to be pretty soul sucking itself, but that’s a different story). It was inconvenient, but what can you do? If you get the letter you have to call in. If you call in and they tell you to come in, you have to come in. I don’t think anyone can fire you for having jury duty, but it certainly didn’t make a good first impression.
