I live in Illinois,am being downsized from a salaried/w bonuses sales
position on Dec.31.I have held a part-time acting job with varying
paychecks of $35-90,an independent contractor position which has added
about $1500-2000 to my income.My salary was in the low 40's in my
fulltime position.In filing for unemployment,will my 1099 acting job
hinder the process or matter at all?

I couldn't find the answer quickly on the Illinois site.  I can tell
you, however, that in some states any money you make from part-time
self-employment is deducted from your unemployment earnings, but it
doesn't affect your eligibility (provided that your self-employment
isn't an obstacle to you finding a full-time job).  In your case,
instead of being able to receive, say, $400 a week in unemployment,
you might be able to receive only $360. I wish I had the information
for Illinois, but I don't.
