To put people’s mind at ease, I have no tests pending and, even if I did, I wouldn’t have any problem passing. I just wonder how true the above is.
First, the cost of testing is not very high. It is not uncommon that the people who demand such testing take place are separate from the people who are responsible for having the testing done. For large corporations, the cost of testing is part of the budget and once it is approved, nobody (except perhaps the purchasing agents who negotiate with the testing labs) gives the cost a second thought.
Second, while I suspect that if you pass, you keep your job, I know for a fact that you can fail and nothing be said. While management theory says that employees are a fungible resource, management reality is that very often, they are not. While an employer who has an employee that had a habit of showing up for work drunk, stoned, or tripping isn’t likely to want to keep that person, if their top foreman of their most productive department should come up positive for pot after a 4-day plant shutdown, they may just forget about it. If the employees had records of their results, that could cause problems.
