The term "greasing palm" usually refers to bribing someone in order to make them do something illegal or unethical. Antonyms for this phrase could include "playing by the rules," "observing ethics," "maintaining integrity," or "being honest and upright." Instead of "greasing palms," one could advocate for fair and transparent methods of achieving their goals. This could involve promoting merit-based decisions, avoiding nepotism or cronyism, and upholding legal and moral codes of conduct. Ultimately, using proper and lawful channels to attain success is a much more sustainable and reliable approach than resorting to corruption or underhanded methods.
