How should I process two W-2s from the same employer?

BNoble

I had received two W-2 forms from my company for this tax season. I believe one was from my time as an hourly employee early last year and and the second is for my time as a salaried employee from the second half until the end of last year. They have the same EID number. Should I add the numbers for each box to enter them into the tax return?
