That's probably it. Just show up on time for your shifts and do your job correctly. That already makes you a better worker than most. I guess you could try to take extra tasks and whatnot to show you're really willing to work whatever area, but it depends if this is just a summer job or you plan to stay for a couple of years.
Until I find something better 😛 I mean, its a job and thats something that might be hard to find right now.
Does anyone know the best time to ask about cross training. Is is something I should ask right away or should I wait a little bit?
