We lived in the US for several years - DH was there on a work assignment. He works for a British company, that at the time we were there, he’d worked for for 15 years. Same company, same department - actually working with a lot of the same people he had worked with from the UK as international connections across the teams are pretty common.
The two experiences could not have been more different.
In the UK business he had been regularly praised/rewarded/promoted for his managerial skills - specifically his ability to cut through the BS and get the job done efficiently and to a very high standard - saving everyone time, and the company money. He was seen as an excellent manager who cared well for his team and promoted a healthy work-life balance while still producing some of the top results in the company year on year.
In the US he was told he was lazy, and he was a poor manager and he would never develop further in the company because he wasn’t at his desk 7am-9/10pm. The fact that he had a happy team and the work was consistently done to a high standard, and the time he saved by cutting out the time-wasting BS, meant he could lean into other teams and help them out with problem solving when required, thus doing more than he was actually paid for, was irrelevant. It was all about appearances.
He knew by reputation it was a bit like that before he went, but I think because he’d been sent on a (very expensive) ex-pat package to the US business precisely because of how good he was at his job, and because he’s not afraid to speak his mind, even to the highest execs, which is generally seen as a positive in the US, he thought he would be ok. He was so shocked when his boss actually told him he’d do better to be sitting at his desk looking busy, even if there was nothing for him to do, than being at home with his family effectively on call as he was available to answer emails or log-on if required 24/7.
Much as we loved our time in the US, and still see it as our second home now, moving back to the UK was the best thing we could have done for DH’s career
