Kaiser Aluminium: Returning 1,000+ Workers After a Two-Year Lockout

How Response planned the return-to-work process at Kaiser's Mead smelter after an industrial dispute. It was completed in 21 days, the fastest of Kaiser's five plants.

The Challenge

In the late 1990s, Kaiser Aluminium's smelters in the north-western United States entered a major industrial dispute. Contract negotiations broke down in late 1998, leading to a strike and then a lockout of the unionised workforce that lasted close to two years. Under US industrial law, Kaiser continued operating the Mead smelter with a replacement workforce for the duration: 90 per cent local, and mostly unskilled in the industry.

When a resolution finally came, the ruling gave almost no notice: a two-week arbitrated settlement period, then 21 days to complete the entire return to work. The two workforces were required to have a complete ‘cold-seat’ changeover. They would not meet, with only a four-hour handover break between them.

The Strategy

Response's approach was to make the return-to-work process something the business's own leaders owned and ran directly, rather than an HR-led administrative exercise. Every member of staff at the Mead plant was interviewed in small groups over two to three weeks, surfacing around 400 individual ‘critical issues’: their fears, concerns and predictions about how the return would go.

Those 400 issues were consolidated into 12 categories and handed to individual managers to own, each developing a plan and, where needed, assigning sub-tasks to teams across the plant. A dedicated return-to-work team, made up of six operating and service managers plus HR and organisational development support, reported back to the general manager's team every two weeks, tightening to more frequent reporting as the arbitration date approached.

What Changed

Specific training was developed and delivered for supervisors and leaders at every level, built around the systems leadership models already in use at the plant and integrated with the existing Working Together programme. Training focused on predicting how the returning workforce was likely to react, based on hypothesised mythologies about both groups, with role-play used to de-stress the transition and build real skill.

Daily department and plant-level reviews were run, with decisions relayed to all staff by email the same day. Leaders were kept as the direct, accurate channel for every issue raised by their people. Pay concerns, grievances and safety issues were relayed leader-to-department-and-back, not routed around them to a support function. A month into the return, a sample of staff were personally phoned by HR to check how the process had actually felt from their side; a further leadership review followed around four months in, asking plainly where the systems leadership models had been used well, used badly, and missed altogether.

The Results

The return to work at Mead was completed within 21 days, the fastest of Kaiser's five affected plants, in a more complicated environment than the others due to a concurrent regional power crisis forcing capacity cuts.

Critically, there was no dip recorded in either operating or cost performance through the changeover, and records were set for safety and production performance in October and November, and for the 2000 year overall. There was a slight short-term dip in safety performance, which the plant's own leaders attributed honestly to people returning to physically demanding work for the first time in two years, rather than to any failure in the process itself.

Where It Led

The plant's own leadership team judged that they came out of the return to work feeling genuinely in charge of the process, with the authority and support to handle problems directly as they arose. It wasn't treated as a side project. It was core to their own accountability as leaders. In the years since, changes to the regional power market forced Kaiser to shut down capacity at both its north-western plants, an outcome no return-to-work process could have changed. Response's own account of the case study doesn't shy away from that ending. It's included here because the leadership capability the process built held up regardless of what came after it.
