BPH is still king. It's the first thing the red shirts look at on their screen.
When you pull into the trailer, evaluate it quickly and determine what you need to do. Need to put up beams? Get your beams up, place your board down (if needed), start your rope. Secure your freight, and bounce. Do it right the first time, nothing worse than having to get called back to fix some shady load.
Don't overthink it. Is someone loading eight skids in and they're three skid in? Drop your freight and come back. Or, give them the checker and let them load it. Move on. Don't sit there and contemplate what you're going to do. You need to make decisions quickly. On the flip side, if you're the one loading eight skids in, and you're half way though, someone rolls through with one skid that can be floored out (or you can work it in), tell them to leave it out and you'll throw it in when you're done. They might return the favor next time you come into a door they're loading.
Don't overthink it. Keep moving.
