Policy and Plan Development

Working with HR representatives and corporate safety administrators, CHASE, LLC tailors written plans and policies to suit the employer, their workforce and the work being performed. Further, CHASE plans respect the employees’ privacy, provide detailed descriptions of exactly what is prohibited, and ensure compliance with DOT requirements and company specific policies. Since regulations change from time to time, CHASE also provides regular written updates; ensuring clients adhere to adopted standards to maintain a Drug Free workplace.

Substance abuse policies vary widely. Some simply prohibit the use of drugs and alcohol, while others state the prohibition and more clearly define the provisions for sample collection and testing both pre- and post-employment. Employers subject to federal drug testing laws must also ensure that their written policies conform to applicable standards. CHASE will work with your company to ensure that your policy and plan meets federally mandated requirements.
