I'd argue that it's not about working overtime. Rather, it's simply about avoiding obviously risky decisions and behaviors. The number one avoidable risk factor involves alcohol. If you're going to drink while away from home, do so in a very moderate way and always with trustworthy friends. That advice applies to both males and females of course, because the rate of assault against males is almost certainly as dependent on alcohol as is sexual assault against females.

Male or female, if you insist on engaging in risky behavior, all society can do is try to pick up the pieces. The best way to avoid becoming a victim is to take responsibility for your own actions. Unfortunately, there doesn't seem to be anyone advocating that obvious remedy. When you point out that women can easily avoid much of the risk, you're accused of blaming the victim.
