I am no expert, but from reading your description it sounds like human error that must be corrected. How would this application have made it past CIO if it did not meet the Ministerial Instructions of having ONE YEAR OF CONTINUOUS EMPLOYMENT in one of the NOC 38 professions? I don't know when you submitted your full documents, but there was an OP Bulletin 173 issued 8 Jan 2010 http://www.cic.gc.ca/english/resources/manuals/bulletins/2010/ob173.asp which states the one year of continuous employment can be made up of several jobs in one or more eligible NOCs. You may want to familiarize yourself with this bulletin as I am not sure whether you were working in the same NOC and with the EMPLOYER since 2003 from your information and it might give you an even stronger case. All the BEST!
