Tomorrow's going to be interesting because we're required to be on then offsite for a function then back onsite? Maybe if we're lucky we'll just go home after the function.
If there is alcohol involved then they can't be back onsite to work after the function because it will potentially be in breach of employment contracts.
Are they shuttling you there or do you have to make your own way? If it's the former then everyone will go home, if it's the latter you got on the wrong bus/tram and ended up home.
