Don Schumaker was working in the shop of Sheesley Supply Co.'s batch plant in Allentown, Pennsylvania, in December 1957 as the ready-mix concrete outfit headed into the cold, sluggish winter months.
So, unsurprisingly, on Dec. 10, 1957, Schumaker and two other shop crew members were laid off. But, company officials told the three men, they had friends at Mack Trucks' test lab. Why don't they interview at Mack and try to work there temporarily — at least until Sheesley could bring them back?
"On Dec. 12, I went to Mack and stayed there," said Schumaker, of Orefield, Pennsylvania.
That's not an exaggeration. Sheesley was the last company Schumaker worked for that wasn't Mack. Schumaker, who turned 80 on Dec. 22, has been with Mack Trucks for 58 years — more than half of the truck manufacturer's storied history.
