Input: Question: I overheard my manager asking "What are you up to?" What does that idiom mean? Is it an informal/negative way of asking?? 
Answer: "What are you up to?" means "What have you been doing lately?". If you add an adverb to the end of the phrase, for instance, "What are you up to tonight?" or "What are you up to this summer?" it can be interpreted as "What are you planning to do tonight?" or "What are you planning to do this summer?".
