I travel on business. Thinking about this summer, I flew out to Shanghai one Saturday night (economy), arrived Sunday afternoon. Got as much sleep as possible, had a day of meetings in Shanghai, then got on a bullet train to Beijing. Two days of meetings, then a 2am flight back to London (economy again), arriving at 6am. Saw my husband and children, did my washing, and was out on a flight to Poland the next day. Rinse and repeat.
The longest I was home over the whole summer holidays was less than 48 hours. By the time the kids went back to school, I couldn't tell you what day it was, I was so tired. On one flight, I was sat for 11 hours next to a man who just happened to keep invading my space and stroking my arm "in his sleep". I had to socialise all day, from breakfast to dinner. The only time I got to myself was when I went to the loo. The back home office work didn't stop, so I had to answer emails, get on calls and coordinate my team from whatever timezone I happened to be in at the time.
Like heck would I be doing that for fun, or would my company be paying for a jolly. In China, I learned some key information that completely changed our business strategy and saved the company millions. Face to face communication is really important in Chinese culture. You don't get nuggets like that from a Teams call, or at least not until you've invested a significant amount of time in building real-life relationships first. In Poland, I used my experience and expertise to walk a new manager through an upcoming external audit, pre-empting findings that could otherwise cause weeks in paperwork or, at worst, suspension of our business in Europe. Again, that's not something you get from a call.
