You are a union organiser preparing for a strike at a tyre manufacturer.  The dispute concerns shift patterns, which the employer has unilaterally changed.  Although the total number of hours worked each week remains the same, the difference between the old and new shift patterns 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 run their lives for years is overturned.  Church, sport and the long-weekend visits of many to their family in the rural areas are disrupted.    They are angry.
