Narrative:

Taking off on runway 21L we were given initial climb out instructions to turn left to 090 and climb to 3000 feet. During the takeoff briefing it was stated by the PIC/PF that we would not return to the departure airport if there was a mechanical malfunction due to the gusty crosswinds and short runways. After taking off we experienced a mechanical malfunction when attempting to raise the landing gear after 400 feet. The main landing gear did not retract but the nose wheel did. We had two green main indications no nose wheel and the red gear unlocked/unsafe light.when the malfunction occurred the sic (second in command); without communicating with the PIC on a plan of action or pulling out the emergency abnormal checklist; immediately communicated to tower that we wanted to return to the pattern (against the takeoff brief agreement and without communicating to the PIC/PF).what followed was a serious breakdown in CRM and a failure to 'aviate; navigate; communicate' in that order as all pilot's primary training correctly mandates.after trying to get the sic/pm to stop communicating with ATC; the sic became angry saying he was trying to 'do his job' and the PIC stated 'well in that case I need you to communicate to them that we are climbing to 3;000 feet and proceeding on a 090 degree heading; that we'd like to go to the nearby class B departure; and then I want you to pull out the emergency abnormal checklist and find landing gear will not retract section and begin reading it out loud'.the sic then stated that he was 'pissed off' and the PIC stated 'too bad'; I need you to follow my instructions.after about 90 seconds to 2 minutes and during this exchange; the landing gear retracted on its own. At this point the PIC directed the sic to communicate to the nearby class B departure that we wanted to change our destination to another airport; which is home base.they asked if we needed assistance and we told them no; since the airplane was now cleaned up. We were given a heading and altitude and a new clearance for home base airport.we continued running the associated checklist during the climb; and stopped at landing gear down. We waited until the appropriate time in the descent and approach to complete it from that point; which we did without incident; and we landed normally.

Title: A CE680 main landing gear failed to retract after takeoff with the gear handle up. Due to a CRM issue the QRH actions were delayed; during which time the main gear retracted on its own.
