Help, Naturalisation Application - work history

[erdnorth]

Hi,
I would like to know if there shall be a problem with my naturalisation application.

I am an Non-EU applicant and got my ILR in Jun 2011.Planning to apply AN form this month.

In 10 years work history, I have an issue. Brief details are as below.
Student work permit : Jan 2005
Proper work permit : Jan 2006
I changed my employer during this time. New work permit : Jul 2007-Jun 2012
But I was made redundant in Dec 2008 and that time there was no rule that employer need to report to HO. I still had valid visa and applied for Tier1 (HSMP) in Feb 2009 and was granted in Jun 2009.
I am an Engineer, quickly got three jobs in Feb 2009 and due to financial pressure, I started working in Feb itself as I worked during my Tier-1 applicaton.
Now will this create a problem in the application? My P60 says I started working from Feb 2009.

Please help. Thanks for your advice
