You are a union organiser preparing for a strike at a tyre manufacturer. The employer has unilaterally changed the workers’ shift patterns. Although the total number of hours worked each week remains the same, the difference between the old and new rosters is significant. Workers who never worked weekends must now do Saturday and Sunday shifts every so often. The beneficial, four-day long weekend that came up during the old shift cycle is also gone. The way workers have organised their family and social lives for years is overturned. Church, sport and the long-weekend visits to the rural areas are disrupted. They are angry.
