1 Aim: to measure the amount of stress experienced by the
sawmill workers and to look for causal relationship on work
satisfaction and production
2 sample: 14 = high-risk workers,
10 = control group workers,
mean age of both groups = 38.4
High-risk workers: cut edged and graded the wood.
Control group: repair and maintenance workers.
All were shift workers and they were paid by a piece rate that was based on group performances.
