Yes, cruise ship staff are allowed to drink alcohol, but they are subject to extremely strict blood-alcohol concentration (BAC) limits and "zero-tolerance" safety policies. For most crew members, the BAC limit is 0.04% or lower at any time while on board, and they are strictly prohibited from consuming any alcohol within 4 hours of their scheduled duty or "on-call" period. Crew members usually have their own dedicated bar (the "Crew Bar") where alcohol is sold at a significant discount, providing a space for them to socialize away from guests. However, random breathalyzer tests are frequent, and being found "over the limit" or appearing intoxicated in a guest area is almost always grounds for immediate termination (dismissal) and being sent home at the next port. The "Above Deck" staff (officers and guest-facing roles) are under even more scrutiny and are typically only allowed to drink in guest bars if specifically invited or during certain sanctioned social events, as they must be ready to lead emergency evacuations at a moment's notice.
