C. Notwithstanding the provisions of subsection B, nothing in this section shall (i) restrict an employer's ability to take any adverse employment action for any work impairment [ caused by the use of cannabis oil ] or to prohibit possession during work hours or (ii) require an employer to commit any act that would cause the employer to be in violation of federal law or that would result in the loss of a federal contract or federal funding.
