NueDesign Cricut Machines & Supplies

I work for a company that does not have office space so we work from home. They supply the computer, however we had to puchase our own copier. Previously,we were reimbursed for one ink cartridge per month, stamps were paid and a small amount of money was paid towards our internet service, since everyone works at home; now they are no longer reimbursing us due to the economy. Also, our job entails a lot of travelling and we were reimbursed for our mileage, tolls and parking each month. Now we are paid a set amount each month and that amount does not cover our true mileage, tolls and parking. Is this legal? Thanks!
