Re-working is the process of revising, editing or modifying something that has been previously created. Its opposite, also known as the antonym, is "leaving as is". When you "leave as is," you choose not to change something in any way, shape or form. This is often used when editing a document or when deciding not to make any needed modifications to a project. While re-working suggests an active approach to editing, choosing to "leave as is" is a more passive approach that often narrowly refrains from offering any additional input. Sometimes leaving something alone is the best course of action.
