I have been working for an Albertson's store in Colorado since July 26 and I have still received no pay.

Their normal payday is every Thursday.

They were using the excuse that my drug test had not come back yet. When it came back unusable or "dilute" They had me take another one. That was last Wednesday a week ago. I'm worried that this Thursday will roll around and I will still not be paid.

Colorado law somewhere reads that employers have 30 days or one calendar month to pya employees but I'm not sure if this applies to me.

I'm wondering what my next move should be if I am not paid this Thursday.

I would suggest that you talk with your manager, as a first step. If that doesn't work, you can file a claim with the Colorado Labor Standards Department. They can be reached at 1-888-390-7936.

Let me know if you have any other questions.

The manager of the store is the one that keeps puting me off. I contacted the CO Div of Labor and they said that the store had ten days after the first pat period to pay me. We are well past that.
They also said something aout the employer having 30 or one calendar month technically to pay me.
Tuesday will be 30 days and next Thursday will be one calendar month. If I don't get paid by that thime I'll have to quit I suppose and file a Wage Claim

You don't have to quit to file a wage claim. File a wage claim. I can't stand employers who delay wage payments. Good luck.

But won't they fire me anyway if I file a wage claim?

No, they shouldn't. Some states have protections against retaliation. You can talk to the Colorado DOL to see if Colorado has that protection.
