This book was published by J. Weston Walch and carries a 1987 copyright date. It is set up to be a full course in vocational English containing the writing process, business letters, resumes, spelling, using reference materials, completing forms, vocabulary, editing for errors, grammar basics and more. There are practice sheets, unit quizzes, and cumulative tests all in a spiral-bound package. I've used this in my lower-level freshman English classes successfully.
