That would be fine if there was a qualified delivery driver available. Only time I do ground work is when there is no one else available. Just like supervisors working after exhausting all means. You are just cherry picking the contract to line your own pockets. I bet you would be the first one to turn down extra work and then file on your fellow Teamster trying to feed their family. Guys like you give Unions a bad name.
So as a career part timer, you "feed your family" on extra work?
You might want to reevaluate your priorities.
But since you asked, I never filed on isolated individual occurrences of air drivers doing ground work, rather wholesale violations, over long periods of time, that could be construed as a business model.
Either way members like you, that think as you do, make the Union weak.
