Note: Pearson correlations; Cronbach's α's are presented in the diagonal (given in italics). N = 283; r≥ ≥ │.12│ p ≤ .05; r ≥ │.17│ p ≤ .01 (two-tailed).

All measurement models contain all variables at both measurement time points (illegitimate tasks, feelings of resentment, and irritability); Model 1 = illegitimate tasks as single construct with the two subscales as indicators; Model 2 = illegitimate tasks as second-order construct, with unnecessary and unreasonable tasks as first-order constructs; Model 3 = unnecessary and unreasonable tasks as two separate constructs (r _{unnT1−unrT1} = .62, p ≤ .01; r _{unnT2−unrT2} = .63, p ≤ .01); Model 4 = illegitimate tasks as single construct with the eight items as indicators.

^a0 = f; 1 = m; ^bin percent of a full time equivalent (FTE).
