Endings with valued clients may lead you to consider establishing a different kind of relationship - perhaps a social relationship or a friendship. Several ethical principles pertain to this issue. For example, the NASW code (1999) indicates, "Social workers should not terminate services to pursue a social, financial, or sexual relationship with a client" (Section 1.16. d) and "should not engage in dual or multiple relationships with clients or former clients in which there is a risk of exploitation or potential harm to the client" (Section 1.06. c).
Worker-initiated contacts with former clients are seldom helpful. Professional relationships should not be converted to personal or social relationships. However, you should feel free to greet and speak briefly with former clients that you might see on the street or in a social setting. Say hello and exchange a few words, especially if the client acknowledges you. You may occasionally receive an invitation to a former client's college graduation or wedding. You are not obligated to attend such functions but you may do so as long as the former client initiates the invitation and you do not use the occasion to establish a longer-term social relationship.
