susanna and i have a slightly different take on this and the notion of security -- feeling secure is key to good attachment in relationships, it does not mean that that relationship is forever (not secure in that sense). trust is often a necessary foundation for security (if i think that bank will keep my money safe, i will feel more confident and secure that it will). security can also enhance trust. so the two are linked but represent different aspects of how we feel safe. if we dont feel secure enough at work, we will feel stress, perhaps hold back on committing, etc. this is what we were trying to express. thank you for the feedback that we were not clear enough!
