Why You Should Have a Drug-Testing Policy In Place
Having a drug-testing policy in place isn’t about showing a lack of faith in your employees, instead, it shows a commitment to safety. Having a drug-testing program in place shows employees, as well as future clients, that substance abuse will not be tolerated on the job and that your company is committed to keeping the job sites safe for everyone.
Having these policies in place will make it clear that your company has high employment standards and employees who know they will fail, likely won’t even comply which will save you time and money.

In addition, we also have access to a large number of testing facilities that can be used by our clients. This is ideal for clients who don’t have the necessary space, which is often a concern in the construction industry, but these sites can all be used for after-hours testing if necessary.

Drug Testing in the Construction Industry
Employee drug-testing for the construction industry is not state or federally mandated, however, more and more construction companies are implementing drug-testing policies.
These policies help keep the job sites safe and the company accountable.
At a construction site having someone under the influence can be extremely dangerous and while nothing can eliminate that risk, having a drug-testing policy in place can significantly reduce it.
Because drug-testing for the construction industry isn’t federally or state-mandated, there aren’t the same guidelines that there are for other industries, though privacy and employment laws need to be taken into consideration. Because there is less structure, it can be confusing knowing where to start and that is where Preferred Alliance comes in.
We have experience working with many companies in the construction industry and helping them design a drug-testing system that works for them and we will put that experience to work on your behalf.
