I am on call for tech support 24/7 so that in itself requires me to work from home.  My employer also allows me to work from home Monday thru Thursday in my home office.  I go in to the office on Friday's for meetings.  I have a cubicle where I sit, but there is no computer equipment for me to use to work so I bring my laptop.  Can I claim my home office, electricity, etc as a deduction?  I am in Illinois.  Thank you in advance.
