My Husband's best friend of 20 years is his best man at our upcoming wedding. However, he just got a new job in a new field where he is initially supposed to work weekend shifts Fri-Sun. When my husband speaks to him on the phone, it sounds like he's preparing to tell us that he won't be able to attend the wedding due to his new job. First, he said he may only be able to go for one night and earlier today he was saying how his shifts were 6 to 6 and he was nervous about getting back in time on Sunday. I honestly don't know a lot about how PTO is laid out for shift work but is there any advice for how he could request this time off even though it's 2 months into his new job? Are we being too optimistic assuming he'd be able to get the weekend off still since he is in our wedding?
