How do I let someone know an employee is using marijuina on the job?

They work at Hardee's. If there doing there job still why get involved.

Call the corporate office and give them the store number and the employee's name either way if it's legal or not it's still not right to use it on the job

I don't think I would. In a few months it will be legal anyway

If you know when they'll be lighting up, contact the local Police Department.

But it isnt now.
