Saying No To Promotions Away From Tech?

lunchlady55 writes "I have been happily working for my current employer for five years. After moving up the ranks within my department from Intern to Technical Lead, a new manager essentially told me that I have to move into a different role, oriented toward 'administrative duties and management.' We are a 24x7 shop, and will now be required to work five 8-hour days rather than four 10-hour days and be on call during the other two days of the week. Every week. Including holidays. My question is: have any Slashdotters been forced into a non-technical role, and how did it work out? Has anyone said 'No thanks' to this kind of promotion and managed to keep their jobs?"
