Am i legally required to sign any sort of termination paperwork? Isnt my check supposed to be ready within 72 hours?

Question

So on August 12 I put in a three week notice to my employer stating my resignation. I ended up being fed up with the lies and behavior or my employer and sent a text telling her i quit around 4pm on saturday the 27th, two weeks of my three in my notice. She (my employer) is now telling my significant other, who also quit the same employer, that we need to come in and sign something for our checks, that wont be ready until 12pm tomorrow, september 1st. I am an oregon resident if that makes any difference in anything. Am i legally required to sign any sort of termination paperwork? Isnt she legally obligated to have my check ready within 72 hours of my resignation?

Mr. Michael O. Stevens · Answer

You are not required to sign anything as to a termination, other than if you are receiving a severance. As to when your check with all of your final pay is due, since you quit with less than 48-hours notice (the three week notice was moot when you quit earlier), your final pay is due as follows: 
 
"Except as provided in paragraph (c) of this subsection, if the employee has not given to the employer the notice described in paragraph (a) of this subsection, the wages become due and payable within five days, excluding Saturdays, Sundays and holidays, after the employee has quit, or at the next regularly scheduled payday after the employee has quit, whichever event first occurs." 
 
If tomorrow is beyond when it is due, I would contact a local employment law attorney to discuss, as there are some hefty penalties.
