Other antonyms for "most band-aid" include long-term, sustainable, lasting, enduring, substantial, and fundamental. These antonyms apply to a situation in which the root cause of the problem is addressed, rather than just the symptoms. For instance, applying a "most band-aid" approach to a poorly performing employee might involve providing incentives or rewards to temporarily increase their productivity. The opposite of this approach would be to invest in their training and development, to build their skills and capabilities for the long term.
