An inspector enters a business, asks to see where the staff schedules are written, and the owner stares at the empty wall. That scene repeats every week in shops, workshops, and offices across the country, and it almost always ends in a citation. The work schedule sheet is one of those papers that almost no one has posted until the inspection arrives, and then it is too late. Here I explain what it is, what exactly article 6 of Law 11.544 mandates, what it must say, where it goes, and how digital attendance tracking covers you when the wall poster falls short.
