When there is reasonable suspicion that an employee is under the influence of drugs and/or alcohol, management reserves the right to require testing. Employment may be suspended (with pay) until the test results are received. The employee’s refusal to submit to testing may result in disciplinary action up to and including termination of employment. Random or General Testing Employees may be tested on a random or periodic basis to the extent permitted by applicable state and federal laws. The refusal of the employee to submit to testing may result in the termination of employment. Use of Qualified Laboratory All testing is done by a qualified, licensed laboratory designated by AJK. All collection sites and laboratories will administer and analyze the tests pursuant to approved guidelines and certified laboratory procedures in order to provide stringent and thorough quality control measures. Confidentiality All employee records are kept in the strictest of confidence and results are given only on a "need to know" basis.
