expansion did not have much impact on wages, benefits and working conditions. As one local historian put it, Robert
Sprague's view of his employees was "paternalistic". In March 1970 a major labor strike started and affected all areas of the company. The strike lasted 10 weeks and was ultimately settled by a federal mediator. While Robert C. Sprague and the Union representatives shook hands after the settlement, the results had a negative effect on future of the company, its management and employees.

The publication was divided into two sections. Part 1 discussed the company accomplishments, achievements and the loyalty of Sprague employees, often spotlighting individuals. Part 2 contained employee announcements: births and weddings, social activities, and other family events.
