How (not) to encourage drugs testing compliance

This post is not about my position on the drug war, which may or may not be guessable based on my libertarian tendencies.

This post is about employee drug testing. Employees generally don't like it, whether for tactical or philosophical reasons. So how do you decrease the pushback against drugs testing in the workplace?

By having the direct supervisor tested every time a reporting employee is tested. In the case of a new hire, the manager doing the hiring gets tested. Simple, no? It gets the company even more of whatever they are trying to get by drugs testing. It is leading by example. Management is not asking anything of the worker that they are not willing to do themselves.

The opposite case is hypocrisy: drugs testing is good for worker bees but not bigwigs.
