Questions from employers in this region
We are a Camp Shelby base support contractor in Hattiesburg - what drug testing program do we need?
Federal contracts above $100,000 require a written drug-free workplace policy under the Drug-Free Workplace Act. Camp Shelby installation access requirements may impose additional conditions for badge issuance. Most base support contractors implement a full testing program covering pre-employment, random, post-accident, and reasonable suspicion testing. Consult your contracting officer on specific installation requirements. We perform on-site collections at your Forrest County facility for any program your contract requires.
We run a motor carrier on US-49 between Hattiesburg and Jackson - can you dispatch to our terminal for DOT random collections?
Yes. Provide your terminal address, CDL driver pool size, and preferred window at booking. We confirm routing and collector availability before you finalize the draw.
Mississippi has a medical cannabis program - how does that affect our manufacturing workforce drug policy in Hattiesburg?
Mississippi Code Section 41-137-37 explicitly allows manufacturers to enforce drug-free workplace policies and act on positive cannabis results regardless of medical cannabis card status. Your written policy must be specific, consistently applied, and reviewed under Mississippi employment law. Policy enforcement decisions are the employer's responsibility.
