Name change for this.
I work in a large multinational that makes billions in profit every year. I had to travel to Paris for work. They were being very stingy with the budget, and I could only afford the cheapest hotel on their "approved" list and had to take public transport. The hotel had reviews from the past saying there were bed bugs there.
I now think I have bedbugs - I'm going to the doctor for a diagnosis. If it turns out I do have bed bugs, could I get some kind of compensation from work? What evidence would I need? Who would I need to talk to?
