UPS pilots strike over network changes (1997)
About 185,000 Teamsters walked off the job at UPS for 15 days, mostly over the company's use of part-time workers. The strike halted much of UPS's package flow and forced a national spotlight on how the network is staffed.
UPS lost an estimated $600 million and had to convert thousands of part-time jobs to full-time under a new contract.
Labor terms became a lasting constraint on how quickly UPS could reshape its workforce and network.
Today's restructuring cuts tens of thousands of jobs, but UPS says it is using attrition and voluntary buyouts, not forced layoffs. The 1997 history explains why the company is cutting carefully rather than fast.
