My (US) company is sending me on a trip (about a 4 hour flight away) spanning Weds to Weds. The organization I'm visiting will be closed over the weekend, so I don't expect to do any work on Sat and Sun. However, I'd still be stuck away from home and would have to cancel my weekend plans.
I'm salaried and my work typically has a flexible schedule, e.g. we can usually get permission to work on weekends and take off a week day as long as we work the full 40 hours.
Would my company be morally or legally obligated to pay me for Sat and Sun (that is, include them towards my 40 hours for the week), even though they are not typically workdays and I wouldn't be able to get any actual work done?
