Naval honours and workplace power disparities

Are there historical parallels for revoking a former naval leader's knighthood?

Revocations have happened before, but no specific precedent is named. The ethical objection concerns a substantial disparity in workplace power.

Revoking an honour is accepted as something that has happened before, though no specific historical case is named. Meeting a partner at work is considered understandable because work occupies so much of many people's lives. A substantial power disparity creates the more serious ethical concern. A separate recommendation favours relationships across departments, allowing some distance if the relationship ends badly.
