At 004 (Little Rock) we have two NDXP PSE drivers that work Monday thru Thursday from 7pm to 5:30am (10-hour shifts). We also have two PSE/Checker Combo's that work the same days and hours in case one or both of the PSE drivers are off due to vacation, illness, etc.. These two PSE/Checker Combo employees will work as checkers on the dock for the most part, but by having them it prevents any bid checkers from being forced off the dock for PSE work and the possibility of running out of hours as the closest start time of a bid checker is at 3pm. One of our NDXP drivers goes to Springfield, MO. and the other one goes to Shreveport, LA. and both of them are roughly 8 to 9 hour trips there and back plus the loading and unloading time at the exchange point.
