No work is being done on anything. But time is still passing....... and the force still pressing......

Work is only done when a force moves a mass some distance (lifting the rock off the plain against the gravitational acceleration). Or when a force accelerates a specified mass for a period of time. Acceleration involves a length dimension.

Therefore "Work" involves a length dimension. Distance.

I don't think that much in physics theory these days. I hope you understand what I write here. I knew you weren't correct here but to my astonishment I initially found it difficult to enunciate why.
