INTRODUCTION

voice: “constructive change‐oriented communication intended to improve the situation” (LePine and Van Dyne, 2001)
“positive voice” - improving the situation at work
voice in the work ~ positive attitudes toward jobs and org.
research within social exchange theory (Blau, 1964) - norm for reciprocity (Cropanzano & Mitchell, 2005): individuals satisfied with their work envi. use more actively their voice. Assumption that employees use voice to regulate social exchanges w/others.
What about the possibility to regulate personal resources as well? Voice as a response to stress, to protect resources, accumulate more resources (resources acc. to conservation of resources (COR) theory - Hobfoll, 1989: limited personal res. and motivation to protect/save them). Voice instrumental to achieve it (costs some res. but if used strategically may conserve/give more in return)
stress-voice relationship? Fear of wasting energy in using voice or stronger using it to obtain another res.?
obtaining meta-analytic data to test the stress-voice usage relationship, formulation of pairs of competing hypotheses:

Job stressors and strains are negatively/positively related to voice
Social stressors and strains are negatively/positively related to voice
Organizational stressors and strains are negatively/positively related to voice
Voice behavior is negatively/positively related to in‐role performance, creativity, and implementation of new ideas

METHOD

looking for field studies published in or before 2010, which examined employee voice and its correlates:
- keywords: employee voice, suggestions, opinions, and ideas etc., + conf.papers, dissertations/via ref.lists
- wanted: voice behavior at the individual level of analysis (not group-wise or org.-wise)
- wanted: correlations between voice and any other key variables in the study
- only those that operationalized voice as “positive”
55 articles, 2 unpublished dissertations, 1 conference paper = 66 independent studies
51 % USA, 40 % other Western countries 9 % Asia
3 % -1990, 18 % 1990-1999, 79 % 2000-
71 %: self‐report measures of voice, avg.rel.: α=0.77; for rest: α=0.88

RESULTS

ad H1) employees who reported higher levels of job stressors and strains also reported less use of voice
ad H2) social stressors and strains are negatively related to voice, stronger than H1
ad H3) organizational stressors and strains are negatively related to voice
in all cases support for resource conservation tenet (7/10 signif.)
ad H4) opposite, here resource acquisition premise is valid („voice behavior is positively related to in‐role performance, creativity, and implementation of new ideas“)

DISCUSSION

COR theory (Hobfoll, 1989) is a useful alternative lens (to the reciprocation) for
1. explaining the motivation behind the use of voice and for
2. the effects of voice on performance behavior
resouce conservation argument works for H1-H3, resource acquisition for H4
„exercising voice depletes resources; therefore, when employees already face major workplace stressors, they are less likely to offer their ideas and suggestions“
„voice contributes to overall productivity because voice enables employees to acquire resources that can be used to improve performance in other domains.“
Catch-22-style result: „workplace stress creates a negative spiral effect; employees who are highly stressed are less able to accrue additional resources to turn around their future job performance … and vice versa“
„up to some optimal point, stress motivates employees to keep focus and to work hard at the task at hand. After that point, too much stress may lead employees to divert their attention to conserving and protecting resources instead.“
since Human Relations School 1940-1950s „managers have been urged to encourage employee voice“, benefir of positive recirocation… but the willingness depends on the level of stress –> inhibits the use of voice
„key to energizing greater voice behavior is improving workplace conditions for employees“
360‐degree performance appraisals might be more appropriate than supervisor ratings alone when assessing voice

Nejde o klasickou metaanalýzu, ale o originální výzkum který má jako zdroj dat jiné studie, kde hledá dříve nezkoumané vztahy. Výsledky zapadají do „HR“ přístupu, a naznačují chování „buď a nebo“ kde v případě dobrých výchozích podmínek existuje tendence se vyjadřovat a zlepšovat věci, v opačném případě si ale jedinec radši svou energii drží pro sebe a na zlepšení okolí rezignuje. Pro zaměstnavatele je důležité postarat se, aby měl prostředí, kde zaměstnanci spadnou do zpětnovazebně se posilující spirály která zaměstnancům dá motivaci se vyjadřovat a usilovat na zlepšování procesů, vztahů… atd. ve firmě. V prostředí celkového marasmu lidi na práci pro celek rezignují a tento výzkum to vysvětluje nikoli teorií reciprocity, ale teorií šetření osobními zdroji. — Martin Malec 2013/12/31 01:41
