On behalf of my current team - I have been accepted to present on our work at a research conference abroad.
The cost of the conference will ~ $1500-$2000 once flights and expenses are accounted for. This would be covered by my employer.
The conference organisers have requested that we book on "as soon as possible". I have asked for clarification, but for the purposes of this question, let's assume they mean within the next week.
I am planning to resign before the conference date, but not necessarily before the conference "book on" date. I am currently not ready to submit my resignation and probably will have to book the conference before.
If I know I will not be able to attend, am I obligated to not book this course? What do I owe my employer in this scenario?
Other information: My team has 3 other members, one of which could potentially take my place on the conference.
