Im a city driver from Roadway's Brooklyn NY terminal so I'm not from Conway, but maybe the following ties in to what you are saying.
Two drivers from CCX's Maspeth terminal left CCX (1 went to New Penn the other came to Roadway) because, according to these guys, morale has taken a hit. A long time driver was fired for taking off the Friday before his vacation week or some such infraction (I don't know all the details). The thinking of these two guys was, "If they can do it to him, they can do it to me."
The guy who came to Roadway thinks that they're trying to get rid of all the higher paid oldtimers and replace them with lesser paid newbies. Some of the new hires are said to be a horror show.
It is my opinion that upper management in any trucking company does not go around giving orders to cut higher paid employees. However, some terminal managers might interpret some memo to "ecomomize" or "cut cost" as a signal to get rid of top pay people and hire lesser paid newbies.
