11、The following appeared in a
memo1 from a
vice2 president of Alta Manufacturing.
"During the past year, Alta Manufacturing had thirty percent more on-the-job accidents than nearby
Panoply3 Industries, where the work shifts are one hour shorter than ours. Experts believe that a significant contributing factor in many on-the-job accidents is
fatigue4 and sleep
deprivation5 among workers. Therefore, to reduce the number of on-the-job accidents at Alta and
thereby6 increase productivity, we should shorten each of our three work shifts by one hour so that our employees will get adequate amounts of sleep."
