The problem is that company writer's output has become more problematic rather than leas. It is not uncommon for a writer to use so much cited cut and paste information that only 10% of the paper in left with orginal wording. so, I cannot really blame the companies for being stricter with their plagiarism checks. Not that they accurately do their jobs since their in-house software is often faulty. At least they are trying. The writers often complain but fail to understand that it is their own lack of writing skills that cause the problem. Learn from the report. Develop the needed skills. Then watch the reports dissipate over time.
