The Electoral Boundaries Review Committee estimated that the number of electors as on Aug 1, 2015 is 2,460,977 and the 13 Single Member Constituencies (SMC) make up some 14.15% with 348,376 electors.

And since numbers don't lie, we can safely conclude that Lee Li Lian is the most hardworking SMC Member of Parliament (MP) because she has to serve some 34,410 electors.

Here's a list of the most hardworking MP to the least, if they stay on that is.
