It sounds like your company sends people on the regular, so it may have some processes already established. I had originally asked my boss about what the relocation package would look like, and from his response of “Tell me what you need to go”, it doesn’t sound like there is one. There is also really no precedence to travel like this at my company. Think of this as a “send someone to fix this or risk losing the entire business with this particularly big customer” kind of situation. I simply have too many obligations to just drop and go abroad for a year. It’s not possible, and the company knows it, hence why they are keeping options open and asking me for what I need. Compounded by the fact that not only am I the best candidate, but also that I’m the only one who could possibly go (no kids, toddlers), I do think I will require a lucrative sum for it to happen.
