Since the Fourth of July is tomorrow and a hell of a lot of people will be heading to work the next morning, you’d think everyone would be responsible and take it easy on the heavy drinking.  

And you would be wrong.

According to a new survey, one out of five people who have to work on Thursday say they expect to be hungover or extra tired that day.

And when you just look at millennials, that jumps up to 30%.  In other words, around one out of three of your coworkers who are in their 20s or 30s will be hungover on Thursday.

And in some ways, you could look at it as a silent protest against their jobs.  Because the survey also found 14% of people say they resent the way their company handled vacation time this week.
