I am in a US graduate program and our professor has made a requirement that we have to participate in a program called VITA. It is a volunteer tax aid program for low-income individuals. As a volunteer you usually only review W2 and Social Security information. Not enough undergraduate students volunteered so they decided that the graduate students should be required to help. We (the graduate students) volunteered as undergraduate students and it does not benefit our learning.
Because of this requirement, I will now have to make up 8 hours a week AT my real job, which also does taxes, to not have my pay cut. I am a Staff Accountant.
How can I convince my professor to not require this volunteer work?
