Summary This paper advances the understanding of managerial voice endorsement based on a self‐regulation perspective. We suggest that although managers might potentially benefit more from employees' upward voice when they are more depleted, they are paradoxically less likely to diligently process or endorse such voice under ego depletion. We draw from ego depletion theory and argue that when managers are more depleted of their self‐control resources, they will spend less cognitive effort in processing voice. In turn, they tend to reject employee voice due to status quo bias and confirmation bias. We further suggest that the detrimental effect of ego depletion on voice endorsement is stronger when the voicing employee is perceived as having low expertise. We conducted an experience sampling study surveying 62 managers about voice events they encounter at work over 10 days (Study 1) and an experiment with 198 managers (Study 2). These two studies support our hypotheses. We discuss the theoretical and practical implications of our findings.

SYNOPSJSThe structure of oriented polyaniline ( PANI) films were characterized by elemental analysis, FTIR, XPS, SEM, and X-ray diffraction, and their electrical properties were measured as a function of the protonation state, elongation ratio, temperature, and applied pressure. A maximum conductivity at room temperature for oriented PANI films can be achieved up to 500 s/cm with conductivity anisotropy as high as 20 : 1. The temperature dependence of conductivity for both unoriented and oriented films at 77-300 K and applied pressure of 0-11.4 kbar is consistent with the 3-D variable-range hopping model; however, the hopping barrier of oriented films is one order magnitude lower than that of unoriented films. The mechanism of enhanced conductivity for oriented PANI films is discussed. 0 XPS, SEM, and X-ray diffraction and their electrical properties were measured as a function of the protonation state, elongation ratio, temperature, and pressure in order to understand the mechanism of enhanced conductivity for oriented PANI films.
