JobsOC (Jobs On Campus) is the University temp agency for students.  Paid assignments are distributed on an adhoc basis throughout your time studying: https://www.ncl.ac.uk/careers/jobs/opportunities-on-campus/jobsoc/#jobsocoverview and therefore JobsOC temp workers are not entitled to a University Staff or Associate Staff Smartcard. 

As a JobsOC member, please use your student smartcard for ID and Access purposes during your paid assignments.  If there is a problem with buildings access, discuss the problem with that building operator on an individual basis: https://services.ncl.ac.uk/itservice/core-services/smartcards/smartcardaccessintobuildingsandrooms
