Worked lots of shift work back in the day. EOWeO, 7on-7off, 14on-14off, 28on-28off, southern swing, reverse southern swing (proven to be the worse rotation there is, and I hated it), 6n3, 8n4, straight days, straight evenings, straight nights.
Not sure what Dupont works now, but they use to work the southern swing. Not bad, but it wasn't my favorite. Of course I preferred straight days, but 7on-7off wasn't bad for rotating shift work.
Hope it works out for you.
