Work is done against friction, producing thermal energy

Is this statement correct:

"Work is done against friction, producing thermal energy"?

Thanks

To be as precise as possible - it depends on the situation.
In general however, "friction does work - producing thermal energy." And if you want to be really hardcore, friction converts kinetic energy to thermal energy.
