popsandpip and sarahbumbearer -thank you for understanding me correctly!!
Others - I am not arrogant and do not need to be brought down a peg or two.
I apologised earlier for wrongly assuming that people knew what 'the City' was - not being arrogant, just a symptom of growing up in London, for which I admitted may have been a little shortsighted. Also, it has been in the news rather a lot over the last few years, so it should be somewhat obvious (not being arrogant there either, just perhaps misguided presumption).
I am not unappreciative or boasting of a good job - just being honest - this sort of job demands a lot (as do most other jobs) - and in fact I was being un-arrogant by admitting that I get paid comparatively well for this and should therefore by rights not be complaining.
But my point was that, however much it is the prevailing culture, and however much you might get paid for it (which I won't go into, but suffice it to say it's nothing spectacular, just what would be expected of professional at that level), and however much you have to pretend that you do not have any sort of life / other clients / other conflicting internal demands, that does not justify such a culture or those who perpetuate it. Just because a client might be under immense pressure themselves, should not mean that they should automatically be rude to an adviser for no reason. No matter what the circumstances.
It is no good saying 'that's the city', 'that's the culture', 'that's what you get paid for' etc. - that way of thinking will only perpetuate this selfish culture and the mess this country is in now.
What I am saying is, let's start thinking of each other as human beings, and the realities of that - whatever the job, in whatever part of the country, and however much or little you get paid for it. I only mentioned my situation because I was talking about myself! and - popsandsnip you hit the nail on the head - I wasn't asking for advice (albeit that I posted on AIBU, so that would be expected) - I was just having a rant and letting off steam! I know it won't change, I know what the coping mechanisms are, I know about delegation and time management (although do appreciate the advice Auntiesablishment!).
So, in summary, I am a nice person. I am not arrogant and sorry if it came across that way. Even nice professional people can get upset about something sometimes. And I still hold by my OP (which you won't fully understand the circumstances of as I don't want to out myself!) but within all the professional life that is the 'City' - and within every job everywhere - there should still be that recognition that people are people - we are not superhuman and have to deal with things in a reasonable timeframe (whatever that may be) and unexpected human things may very occasionally need taking care of (e.g. a confidential but essential and urgent visit to the doctor).
SO there.
