Work hours question

[jess_pom]

So our annual meeting is coming up next week and I have a question for y'all:
We have a reception Tuesday night, a "staff appreciation" dinner/reception. Should I include that as time worked? It's a required activity, I'm an hourly employee. This will be my third year but I can't recall how I've handled it in the past.

To complicate matters, there's an open bar, but our handbook states we can't drink while on the job. Thoughts??? Thanks!
