Forgiveness is a health issue.

It may seem less satisfying than holding a grudge and revisiting our moral high ground, but the evidence in favour of forgiveness is clear. It's an investment in our relationships with rewards for both the forgiver and forgiven.

It makes us resilient because we recover quickly from conflicts. The result: less stress and better health.

Doing the honourable thing, especially being forgiving, is a characteristic of successful intimate relationships. Partners who are close find it easier to forgive, because they choose to. They also see their partner's bad behaviour in context - they don't judge the whole relationship on the irresponsibility or ill-chosen words that have upset them today. (It doesn't stop them insisting on better behaviour next time.)

The research has focused on marriage partners, but surely doing the honourable thing, seeing the relationship in context and moving on from anger and resentment applies to working relationships too.
