Honesty/Ethics In Job Applications?

jt007 writes "I am a student in the UK who graduates from a computing course in a matter of weeks, and am starting to look for graduate jobs. One problem though, a friend and I are going travelling in about 15 months (obviously I need the job to pay for the trip!). Do I tell my employers this before I start work and potentially harm my chances of getting the job, or do I just shaft them in 15 months time? I would be interested in finding out in particular how IT managers out there would react to being put in a situation like this? Would it harm any chances of a reference for a future job? So the question is: is it best to keep quiet about my plans, or is honesty the best policy?" Look at it this way: if the company planned to close your office in 15 months would they tell you? If you were leaving in a much shorter period of time I'd think you should tell them, they might be rather annoyed to train you in a job and then have you depart and you might not be able to use them as a reference in the future. But 15 months? If you tell them, not only would you risk not getting the job because of it, your plans might change before then and you'd have lost the job for nothing.
