Eurotraveller,
Thanks very much. I knew I had read that previously but just wanted it confirmed.
pre3l2s,
It does state on the employment history section to indicate whether it was full time, part time, work experience or non-paid / voluntary type work (or words to that effect). I would include things that will support your application. For example I did a weeks work experience (un-paid) at BA some years ago, however I consider that 'significant' as I am applying for a job with them. Hope that makes sense anyway?
Good luck!
