If you lose a finger working with vinyl you have bigger issues to be concerned about.
You need to look at the bigger picture.
You might not have anything to worry about, but if they allow you, by all laws known to man/woman.... they have to be fair across the board and allow that for the welder, electrical guy and the girl cutting all the scraps up for cricut users. Otherwise, someone would sue them for playing to favorites..... or discrimination.
That's what gets me about employees... although owners need them, they usually don't have a grasp of what goes on with the business end part of the business.... of signs. It's all about playing around, making work easier and easier and listening to their favorite music on an ipod or phone.
