The Principle of Equivalence in Einstein's General Principle finds objects in Einstein's accelerating elevators at apparent rest on the floor inside the accelerating coordinate system. The New Age School of gravity doesn't recognize the work being done by the upward accelerating elevator floor because the New School rebukes gravity as a force and in so doing discards the import of the General Theory's acceleration, generating a resistance by the apparently unmoving objects on the floor constituting their 'weight' (Heavy Mass), which is exactly equivalent to their Inertial mass.
The Dictionary of Science (Penguin publishers) defines work:
'done by a force - f - when it moves its point of application through a distance - s - which is equal to fs cos 8, where 8 is the angle between the line of action of the force and the displacement. The delivered SI unit of work is the joule; other units include erg, foot pound, foot poundal.
Since Einstein's General Principle maintains that there is no way to distinguish the effects of acceleration from those of gravity, then gravity as defined by the General Principle is a force of acceleration, and the apparently umoving objects on the floor of the elevator - or the surface of the earth - are constantly beng forced upward, inertially resisting - in proportion to their given mass values - the acceleration against them. Conclusion: work is being done; the apparently unmoving objects are accelerating upward and opposing an inertial resistance to that non uniform motion. Moreover, the so called mysterious 'curvature of space time' is attributable to the same phenomenon - namely, the physical 4-D accelerating expansion of all '3-D matter', where the ever expanding surface of the earth rises up and overtakes apparently falling objects.
Action at a distance such as aquatic, terrestrial and atmospheric tides are effected by the 5th and 6th dimensions of electricity and magnetism (electromagnetism) - a physical extension of the matter that generates it.
