One of the problems not addressed in this article is that Sex offenders gravitate to occupations where they can acquire power over their target group. And clearly any workplace that employs interns and highly motivated low paid staffers willing to do anything to advance their career, and work within a culture where after hours work is  expected and viewed as necessary evil in gaining experience, is fertile ground for a serial offender. One solution is that staffers and interns need a body to look after their interests outside the control of their employer. Remember in this case the employer and the offender are the same in relation to the staffer/intern. What's really needed is some form of worker representation. Allowing interns and staffers to unionize would reduce many of the risk factors associated with this kind of workplace. Union representation would provide interns with some kind of voice, opening other ways a worker can show their worth other than socializing after hours.
