I thought the same and the people at the immigration call centre keep telling me the same. That I'll have 'implied status and can therefore carry on working'. But I've seen a few posts on here stating otherwise.I was on IEC when we applied. We applied September 6th and my IEC expired December 16th. My work permit didn't come until the start of Feb but I got it all the same.
So you must get implied status or mine wouldn't have come when it did, or so I assume.
Do you mind if I ask- did you carry on working between the time your IEC work permit expired and you receiving your new OWP?
