 On 6 May 1946 SS "Argentina" was meant to carry 411 passengers to Cobh, Ireland and Southampton, but she was delayed by a labor dispute.When she was a US Army Transport, "Argentina"s crew had worked a shift system of eight hours on and 12 hours off.Now that she was back in civilian service, Moore-McCormack Lines wanted her crew to return to a passenger shift system of nine hours on and 13 off, but the National Maritime Union disagreed.
