A client in the restaurant industry recently asked me if he could throw away time sheets from three years ago to free up a closet. I told him not to touch anything. The question seems to be about filing and organization, but in reality, it is about legal defense: the day a former employee files a lawsuit, those sheets are the proof that you complied. Here I explain how many years you must keep attendance records and labor documentation in Argentina, why the deadline is not as short as it seems, and why paper is the worst place to store it.
