Narrative: Aircraft X [had] a pre-departure issue [that] contributed to a late and rushed departure and a distraction that affected the crew. Next the Runway XXR departure had a new heading clearance and a new altitude assignment in rapid succession that contributed to the distraction of PM not making the 1;000 foot call while trying to set new heading.Prior to departure there was an issue that required the flight crew to discuss with Dispatch; the FOM and FA crew regarding X deadheading ZZZZ based FAs that had been exposed to COVID-19. With 25 minutes prior to departure I found out that deadheading FAs on my flight had been exposed to a COVID positive crew member for an extensive period of time and would be sitting in Area X with other revenue passengers. They had been cleared to travel by being asymptomatic with no temperature. The outcome was my decision to not allow them to travel on my flight with some pushback and pressure to have them fly. The crew was upset with the way this was handled. Once resolved we quickly finished prep and briefed to get flight pushed.First Officer was flying the departure off of XXR at Intersection 1. Takeoff was normal with the typical busy departure of an initial XX0 heading then back to YY0 heading with an initial level off of 2;500 feet. Just as FO was heading YY0 and approaching 2;500 feet altitude we received a climb to 6;000 feet and a heading of 0Z0 degrees which was more than XA0 degrees to the right. I acknowledged clearance and reset MCP to 6;000 feet with VVM sop. I then started to slowly spin the heading knob to heading of 0Z0 so as not to induce a left turn because it was more than XA0 degrees from our current heading. While maintaining traffic watch and setting the new heading the FO went through 6;000 feet and I saw the 300 feet amber warning and an altitude of 6;380 as the FO was already correcting. This all occurred within a 30-45 second time frame. The remainder of departure was uneventful.Once at altitude we debriefed as a crew and outlined contributing factors:1. Pre-departure issue with COVID-19 deadheading crew members and airline's poor handling and pressure was a distracting and still on top of mind.2. PM while setting MCP with ATC instructions was distracted and missed the sop 1;000 feet call (5;000 feet approaching 6;000 feet)3. IRO started to put times on Master flight plan below 10;000 and was also not monitoring the PF and ATC clearance.




Synopsis: Air carrier Captain reported they overshot an assigned altitude during departure.
