Oklahoma has changed to a medicinal marijuana state. This will not affect employers as long as your workplace testing is up to date, an employee can't use as long as your policy forbids it. Federal Law will never allow it so no changeon DOT. Send us a copy we will critique and make changes as needed for a nominal fee. Remember if you change the policy it must be displayed for 30 days and given in some form to the employee before you start a program. As long a you specify in your rule no pot smoking then the employee has no recourse which means for the employer. You don't pay unemployment.
