Elaine Chao celebrated becoming the second longest serving labor secretary in a classy way. The day she passed his record of 6.3 years, she called former Johnson Labor Secretary Willard Wirtz to compare notes on the job. Wirtz, now 95, and Chao, a buff of labor history, talked about the good old days, and she even told him of hearing Wirtz talk about a steel strike on the Johnson White House tapes. "I didn't even know I was being recorded," Wirtz says. "We had a terrific chat," says Chao. "I hope that I can be as witty at 75 as he is at 95." For the record, the longest serving labor boss: Frances Perkinsduring FDR's four terms.
