Data Analysis
All of the statistical procedures necessary to analyze the data in this study were performed using SPSS 12.0 
professional series software. Descriptive statistics were run to examine the basic integrity of the scales and data set.
The instrument used in the study was first examined for its reliability, mean scores and standard deviations.
Secondly, central tendency and frequency scores were evaluated to discover whether or not there was a normal 
distribution of the variables and to examine any inconsistencies. Lastly, a hierarchical regression analysis was 
applied to investigate whether part-time employees displayed different attitudes and behaviors from full-time 
workers.
RESULTS 
Of the 87 participants, 46% indicated they were part-time employees while 54% held full-time status. 
About 30% (n=25) of employees holding a part-time work status indicated that they want to work full-time. The 
proportion of gender was similar between part and full-time employees; three fifths of the respondents were female. 
While 34% of full-time employees held a bachelor degree, only 18% of part-time had a bachelor degree. 
Interestingly, 62% of the sample held at least an associate’s degree. Most of the full time employees were Caucasian 
(70%). The full time employees (
M
= 28.32) were younger than the part time employees (
M
= 32.65) and they (
M
= 
24.81) had less tenure than part timers (
M 
= 36.55). Lower average tenure among full time workers can be attributed 
to the fact that ten full time employees had less than one year tenure while none among part time employees.
To examine the effects of work status on OS, SS, and OC, a hierarchical regression analysis was used.
Model 1 included only demographic variables; Model 2 contained the demographic variables and work status; and 
PTBFT variable was added in Model 3. As a result of the statistical procedure, work status did not explain the 
variance of OS and SS, after age, gender, tenure, and education were controlled. However, PTBFT did explain the 
variance of OS and SS significantly after work status, age, gender, tenure, and education were controlled, 8% and 
12% more, respectively, indicating that part-time workers with preferred work status as ‘full-time’ showed greater 
perceived OS and SS. Neither, work status or PTBFT had effects on OC.
Furthermore, to investigate the effects on OCBs, a hierarchical regression analysis was again applied with 
the OS, SS, OC, and work status and PTBFT. Gender, age, tenure, and education were used to control spurious 
variances in OCBs. As a result, OS, SS, and OC significantly explained the variances within OCBs of: helping (
∆
R
2
= .35), voice (
∆
R
2
= .15), action (
∆
R
2
= .22), and loyalty (
∆
R
2
= .35), after gender, age, education, and tenure were 
controlled. Model 3 indicated that work status demonstrated significance only for voice (
∆
R
2
=.05) suggesting that 
part-time workers demonstrated greater “voice” organizational citizenship behavior than full time employees (
β
= -
.26). However, PTBFT did not show significance on any of the four OCBs.
