listless - sluggish
Though the word ‘listless’ has elements of lethargy and laziness attached to it, the emphasis is more on a complete indifference to things going on around you. That can be because of a physical or mental problem, or simply due to extreme boredom. In a professional context, it is most commonly used to describe directionless leadership.
