Yeah I’d be less worried about internal pressures (which should be minimal at a halfway decently run org) and more about the externals. I don’t think you would actually end up dealing with anything, but I’d know those reliant huge corps are pissed.
Man, your on-call situation sounds rad! I was salaried and just traded off on-call shifts with my team members, no extra time off. Luckily though, our systems were pretty quiet so it hardly ever amounted to much.
