	Fatigue		Job dissatisfaction
Predictor	β	R² change	β	R² change
*p<0.01. Regression values are standardised coefficients obtained at step 3.
Step 1:
Job control	−0.14*	0.22*	−0.10*	0.26*
Quantitative workload	0.26*		0.27*
Step 2:
Physical demands	0.09*	0.03*	0.15*	0.07*
Supervisor demands	0.16*		0.20*
Step 3:
Control×quantitative workload	−0.04	0.00	−0.14*	0.04*
Control×physical demands	−0.02		−0.04
Control×supervisor demands	−0.01		−0.06
