I work in a UK based company and am about to go on my first business trip overseas to Japan. I'll be going with my boss and the company will arrange everything. Flights and hotels have all been booked through a travel agent and I've been sent details of these bookings.
My question is: how should I go about asking about travel and health insurance for this trip? I could obviously just ask my boss straight up. But he could just say "it's fine the company covers it all". But I kinda want to be sure that there is definitely a policy in place for these sorts of things. Am I being too paranoid? How would be the best way to get definitive proof there is adequate travel and health insurance in place for my trip?
ADDED INFO: To respond to some of the comments about there being a written travel policy covering travel and health insurance, I've checked through all the documents I received when I joined the company and I've not encountered anything on this topic. We are a small company of around 50 employees of whom 30 or so work on a factory floor. Only around 5 of us in senior managing roles would typically travel overseas. There is only 1 person in the HR department. Just to give some context of how my company operates.
