Don't think that's completely fair to us swing drivers. Don't take this as disrespect, it's not in the slightest. Most if not all swing guys appreciate and respect the time you guys all put in. But come on. Like the route I routinely cover. IIRC the driver is at least 25 years my senior, and hell, I'm 31. Unless I dramatically drag my feet all day, there is no way I am not going to run it quite a bit faster. That falls on management and allowances, not on me. I'm not a runner gunner, it's just I don't have 25+ years of delivery on my body. I'm just glad he is a good sport about it, and ignores management.
I was a cover driver for over half of the 21 years that I was in package car. Things have just changed. I'm not throwing all cover drivers under the bus, but when I left PC, about 2/3's of the cover drivers I knew tore up the routes they covered. Maybe I'm showing my age, but back in the day, when we covered routes, we pretty much synced up times with the normal driver. And the drivers who didn't were shunned. In your case, I would have done whatever it took to at least come close to his times. It was just a respect thing, and that respect would go both ways when done correctly.
I'll be the first to say, much of the blame falls at the union's feet. In the years following the strike, the union (in our area, anyway) put us at arm's length. And that's no way to keep and grow union solidarity. Years later, this is what we've got. Many guys don't even join the union, and in the 80's in 90's, that was simply unheard of. In many places, you're lucky to get a decent steward or business agent. As a result, many, many drivers have this "it's all about me" attitude. They bitcchh about how they have to take work off the slower drivers, not correlating that with the speed at which they work. These are many of the same drivers who take shortcuts and run through their day, and then act surprised when their mistakes often get them suspended, or worse, fired.
The best thing I did was go to feeders, where I'm back with all of those old drivers I used cover for when I was a newbie. A lot of us still look out for each other, but so many of those burners are coming back here too, with predictable results. Production, naturally, goes up when these guys come back here, because they bring the zoom-zoom PC mentality with them. Also, not surprisingly, accidents go up too.
So, what's the end story? I guess that's up to you, individually. In my case, it's follow their methods and work at the pace I always have. They get on me a lot, production wise, but they won't get me on safety and doing the job right.
. Drivers like this have made things sticky for all of us.
