What constitutes the 'hidden strain' in construction work, according to worker observations?

Answer

Repetitive tasks coupled with maintaining awkward or strenuous positions

The hidden strain comes from the constant, smaller movements, such as repetitive hammering, twisting while driving fasteners, or the sustained overhead reach, which compounds over time due to repetition and posture.
