"classified information is ONLY supposed to viewed in a SCIF"
No.
No, no, no.
Most classified information is NOT designated SCI. When classified info was mostly paper, it was placed in GSA approved safes in regular 'ole office buildings. You'd get to work, open your safe, and do your work. Most SIPRNet computers are not in SCIFs.
Heck, you can even mail classified documents via USPS. Confidential and secret documents can be sent registered mail.
