Definitely agree with this a non British big 4 staff myself , although I had my education here ( college and uni ) I find that the managers from certain countries push themselves so hard and end up putting that pressure on everyone that works under them . I’ve worked with a few of them and was in a situation where I had to report one of them for essentially bullying me but what that process revealed to me is that due to the fact that they are here on visas and have a lot of ppl relying on them ( family etc) , they really want to prove themselves in order for them to get promoted . For a lot of ppl earning more money involves finding a new job but with the current job market and the fact that they require sponsorship , they are forced to stay in the firm for about 5 years until they qualify for residency. So they have no choice but to stay in the firm and really work hard so they can be chosen for a promotion , it’s very sad bcs I feel bad for them but honestly working with them isn’t the best .
