As a detective solving the mystery of the crossword clue ‘Many front-line workers, in brief’, I first focused on the phrase ‘front-line workers‘. This immediately brought to mind the many brave individuals serving on the front lines of healthcare emergencies, such as paramedics and first responders. Since the clue asks for an abbreviation or shortened term, I then thought about common acronyms for these professions. That is when it clicked – EMTs, or Emergency Medical Technicians. This abbreviation perfectly fit the clue, as EMTs are frequently on the front lines of healthcare emergencies, responding to medical emergencies and providing lifesaving care in critical situations. By using deductive reasoning and utilizing knowledge of common medical abbreviations, the answer became clear: EMTs.
