While two-thirds of (private) companies surveyed in the 2004 report said writing was an important responsibility for workers, 100 percent of the 49 states responding to the anonymous survey said it was. More than 75 percent said they take writing skills into account when hiring.
. . . The report estimates the states spend $221 million annually on remedial writing training, sometimes sending workers to $400-per-employee classes.
The time lost rereading incomprehensible prose can’t be quantified.
