If you want to ignore your constituents and not bother (and are in a safe seat) you might do less than half of that. But MPs, as a group, are very hard working. I also think that the way we select MPs, incentivise them, and manage them is awful and that's one of the many reasons why the institution of parliament is fairly crap. Unjustified cynicism about individuals is unlikely to fix that.
I do apologise for the form letters, though. That's almost always staff work, with the MP signing the result after a brief skim. We got a lot of mail and much of it was repetitive or crankish so the replies weren't always artisanal...
It’s never fun being the boss, but given that you’ve accepted the role you can be a good boss and stand up to your workers, even as much as they try hard to avoid you, or accept your failings and let your organization fall apart. Your choice.
Aah yes, another favourite old-chestnut, the old "well, you can vote differently next time".
Trouble is that one falls apart when you are reminded that the UK has FPTP (First Past The Post) and not PR (Proportion Representation).
As a result, most people's votes don't really count for much, and you end up with safe seats and all sorts of other problems.
But it favours the big-two parties and hence, like many other problems with UK politics and parliament, it will (likely) never change.
FPTP fails hard when parties get thrown into the mix. But that is when you should stop to ask yourself why are you accepting parties in the first place? The Westminster system really isn't well suited to having parties, even if it has grown to accept them.
Its awfully cute when people think that's an acceptable answer, it goes awfully well with that other well known phrase "write to your MP about it".
I know sufficient people across the length and breadth of the UK to know that the reality is that MPs (perhaps especially those who fly the Conservative flag) will do their utmost to avoid and fob off their constituents.
If I had a penny for every person who told me they wrote to their MP and either received no reply or received two-pages of pre-prepared boilerplate that didn't answer the question ... I'd be rich.
As for MPs who have extraordinarily well-paid "advisor" jobs on the side, what's your reasoning for that ?
