I would be very hesitant to cancel the vacation, especially after two years without a proper break and with money already invested in the trip.... Staffing is ultimately a management responsibility, and employees shouldn’t routinely be expected to sacrifice previously approved personal time because an organization is short-staffed.

I’d handle the conversation professionally and acknowledge the difficult situation while explaining that the trip has already been paid for and that you’re not in a position to cancel it. You could certainly offer to help prepare the team before leaving or make the transition easier, but I wouldn’t feel obligated to give up the vacation.

Being committed to your job is important, but maintaining reasonable boundaries and taking time away from work are important too. A healthy professional relationship should be able to accommodate both. more

Hell yes. Take your vacation or have them reimburse you if you don’t go!

I would tell him no and I will see him when I get back, because that job isn’t going nowhere

That's their problem.

Yes. Your vacation is planned, booked, and paid for. I’m sure they had plenty of notice. Don’t feel guilty for their staffing shortcomings. Remember,... you work to live—you don’t live to work. more

I agree, no. That’s inconsiderate and did he she offered to pay all of the money that you would lose if you canceled?

A professional no would be definitely appropriate

I sure would say no! Do you think he would close down his operation so you could take a vacation?
