It depends on your role entirely. Management level or engineer you don't need to be a drinker only on certain social company events. If you are on the Sales team you likely need to be in order to close deals and be part of the team. However I am curious if that is changing within the new Covid ERA. Hopefully this is vestiges of the past and we will move past an alcohol based era. It can be a catalyst for problems in the workplace. To be fair it does have some positive attributes as well. edit: typos
