Electron in an electric field moves opposite to its direction and proton would move in the direction of electric field. The work done to move a charge from point A to B in an electric field is path independent, and the work around a closed path is zero. The change in voltage is defined as the work done per unit charge against the electric field.In the case of constant electric field when the movement is directly against the field, this can be written . W = -qV Perhaps it would help if the equation was written thus: In other words, the work done by the electric field on the charged particle is the negative product of the charge and the change in potential.
