Earlier quoted context omitted.
> every year we take the company overseas for a month (on your own dime, sorry) and work incredibly hard while having a ton of fun. "On your own dime" sounds terrible. Is it optional?
If this position is actually for a full-time employee in San Francisco and the travel is required of the employee, which it sounds like it is ("every year we take the company overseas for a month (on your own dime, sorry) and work incredibly hard ..."), Expensify might want to speak with a competent employment attorney about California Labor Code section 2802 sooner than later.
For those of you who don't like travel, you can go for as much or as little as you want (i.e. none at all). In addition to being in a place you've never been, it's a great way to get to know everyone in the company on a different level and hang out with people you might not necessarily work with on a day-to-day basis.
To each their own, but there are other aspects of our company that make it worth joining as well, and it shouldn't be overlooked if you don't like traveling!
