My sister always gets the car and I need to get to work?

You talk to your parents, ask them if they'd be willing to drive you to work. I'm sure they want you to work, given the way to econemy is. It's hard for people to find a job, so since you were one of the few that got one. You want to be able to keep it. So sit them down and talk or ask them if you can borrow their car when you have to go to work and baseball practice and games.
