Yes,
Either that, or 'exercise' it regularly. My Vit clutch plate would sieze to the flywheel if left undisturbed for a few months over winter - especially if your garage is not a heated luxuary type !
My method is to wedge the clutch pedal down, put car in gear, chock wheels loosely and take h'brake off. Then wind the engine over on the crank pulley bolt, with a spanner. If the car does'nt move you know the clutch has'nt seized! I do this once a month over the winter. That way I don't have wedge the clutch all winter.
