Advice please

It should be fine. Just let them know it was a pre hire commitment and they should honor it. He probably wont get paid but they will at least give him the time off.

Definitely just have him be honest and sincere.

My FH had a similar thing happen where we had booked a trip for the week between Christmas and NYE and he got hired just after Thanksgiving. He didn't get any PTO until 3 months in, so what they did was they basically advanced his PTO. So he got paid for the time we were on the trip, and he just lost a couple days of PTO when he was eligible.

For future reference, for you and for him, the fact that the hiring manager isn't the scheduling manager doesn't matter. Your fiance should have pointed this out when the offer was made. It is the hiring managers job to accept this information and either give an answer, or pass the information onto whoever can answer.

Also, December is a very popular vacation month. While management may be understanding, I doubt his coworkers will be. People with more seniority who couldn't get the time off may be a bit irritated that a new hire is getting it off instead. It may make for a less than pleasant workplace.

Honestly, he should have mentioned this during his interview process, as many other ladies have said. Regardless of who he was interviewing with, that should have been said. When he tells his new manager, during their first meeting, that he is taking time off when he has no PTO... what will his/your plan be if his manager says "sorry you cannot do that"? Will he quit his job? Will you cut your losses on your honeymoon?

I think at this point the best thing to do is have your FH tell his new manager your wedding and honeymoon was planned and paid for before he accepted the job. That he is sorry or not mentioning this before hand, like he should have. And he is willing to take the time off without pay.

My FH was in the same position, but he mentioned it in the interview and they were fine with it. If he's fine with just taking unpaid vacation I don't see why they'd have a problem with it.

Also, at least you're planning 6 months ahead. My FH started this month and the honeymoon is in July, and they were still ok with it.

That's good! Happy to hear it worked out for you.
