STAFF RETENTION AND CONTINUITY   Turnover in today's highly volatile marketplace makes it difficult to retain either full-time employees or contract people. This is another area of STAR difference that provides a significant benefit to our clients.    Highly qualified professionals join and remain with us because our firm has been deliberately structured to serve the needs of associates. We offer them optimum autonomy, exceptional income opportunities plus paid benefits with minimal administrative requirements.    This makes it very advantageous for associates to work within our organization. A number of our people previously were independent contractors but, now, they enjoy 'the best of both worlds' as STAR associates.
