If I knew it was workplace policy, I would be fine with it, because I could work elsewhere if I wasn't.
As someone who has had to deal with plagiarism in courses taught, I am very much in favor of detention on first offenses for failure to cite sources or quote works. It's a serious problem later in life, especially for those in fields where scholarly publication is a key part of work. Plagiarism, accidental or intentional, will get you rejected from publication and (depending on circumstances) could get you fired or open your school/company up to lawsuits.
