Touching pork is not Haram, it is filthy and if touched, hands must be washed. Now what is Haram is that making money directly by selling pork or working as an employee and your payroll is from an income that has pork in it is indeed partially Haram.

The prophet (peace be upon him) said: Allah if made something Haram, income out of it is Haram too. (Ahmad)

In your case, you must look for another job that is pure from any income that includes Haram.

By the time you find that job and you must work to pay extreme necessities of life like rent, food, etc. you can keep your job and donate some money you think equivalent to that portion of Haram income to purify your income.

Allah Almighty knows best.
