I just checked the details on our town council and it says: "The Council has adopted a scheme of Members’ Allowances, under which members are paid £680 per year towards the performance of their duties."
That is just £13 a week! and could easily be used up just in transport/petrol costs getting to various meetings and events.
At the town council level, they are pretty much volunteers who give up their own time to help their local community. The problem is many people are not aware of the democratic process. When local elections come along, they vote for a national party instead of for a local person to represent them, or they don't bother voting at all. They also prefer to complain rather than be part of the process and stand for election themselves. If you don't vote or you are not prepared to stand for election yourself or propose someone else who you do agree with, then you have no right to complain.
