The phrase "laid at one's door" is often used to describe the act of blaming or attributing responsibility for something negative to someone. The antonyms for this phrase could include giving credit where credit is due, acknowledging good deeds or contributions, and taking responsibility for one's own actions. Instead of casting blame, one could show appreciation, praise, or gratitude for the actions of others. Additionally, one could use phrases such as "shared responsibility" or "collective effort" to reflect a team-oriented approach to problem-solving, rather than blaming one person for an issue. It is important to focus on positive language and actions rather than negativity and finger-pointing.
