Using sarcastic words to ridicule others is not a positive and harmonious approach for the team. It may cause conflicts and contradictions and destroy the team atmosphere. When faced with a situation where someone in the team is lazy and does not do anything, a better way is to solve the problem through positive means such as communication, clarifying responsibilities, and establishing a reasonable supervision mechanism. For example, you can find a suitable time to calmly communicate with him about work arrangements and expectations, so that he knows his responsibilities; or you can review the work process together to see if there are any unreasonable places that cause his poor work status; you can also set some team goals and incentive mechanisms to stimulate everyone's enthusiasm and sense of responsibility. If you really want to remind him in a more humorous way, the following words are for reference only. Pay attention to the tone and occasion and try to be friendly: "Hey, it seems that there is an invisible man in our team. I can't find his shadow when I work." Or "Is there a mysterious force that makes our colleague's work energy disappear recently? Why don't you take action?" But it is still recommended to give priority to the method of actively communicating to solve the problem.
