Abstract
Objectives: Considering the importance of employees' behavior in service organizations and its significant impact on their success and failure, the present study investigates the environmental and ergonomic factors affecting the mental health and behavior of employees in one of the branches of Islamic Azad University.
Methods: The present study is applied in terms of purpose and descriptive-correlational in terms of data gathering and analysis. The statistical population of the study includes: 315 employees of Rasht Branch of Azad University, out of them 196 people were selected by random sampling method and the necessary data were collected using a questionnaire. Structural equation modeling and SMART PLS3 software were used to test the hypotheses.
Results: According to the findings, workplace layout affects on use of work equipment (0.389), use of office chair (0.252) and environmental conditions (0.538), but the effect of workplace layout on the posture of employees was not confirmed in 5 percent significance level. Also, the effect of posture (0.586), layout (0.440), work equipment (0.458), office chair (0.345) and environmental conditions (0.550) on public health and also the effect of general health (0.690) and environmental conditions (0.158) on employees’ behavior is significant. Examining the indirect relationships of the research model also shows that workplace layout affects employee behavior through the general health and environmental conditions. Workplace layout influences employees’ behavior through work equipment, office chair, environment conditions and general health.
Conclusion: The indirect effect of workplace layout on employees’ behavior through public health has the highest impact (0.304), therefore, making policies for the general health, can improve employees’ behavior.

Abstract
Objectives: Chronic neck pain is one of the most common musculoskeletal disorders that has a great impact on people's quality of life, health, and work efficiency. Due to the high costs of drug treatments, the search for simple and low-cost treatment solutions is inevitable. Stretching and tissue release techniques are effective solutions for correcting skeletal-muscular disorders. Therefore, this study aimed to investigate their effectiveness in controlling pain and improving the performance of people suffering from non-specific chronic neck pain.
Methods: In this semi-experimental study with parallel groups and pre-test-post-test design, 39 patients with non-specific chronic neck pain with an average age of 25 to 45 years, in a non-random and available form, were selected from the office workers. Individuals were randomly assigned into three groups of traction stretch, release, and control, and received interventions for six weeks. At the beginning and after the completion of the interventions, pain intensity, qualitative fatigue, and quality of life were evaluated using the visual measure of pain, multidimensional fatigue questionnaire, and SF36 questionnaire, respectively. To compare the averages, one way ANCOVA a mixed analysis of variance test was used.
Results: Intra-group comparisons showed that pain intensity, quality of life, and fatigue improved significantly in both intervention groups (P<0.05). Stretching and release exercises both had a significant effect on improving the variables (P<0.05). However, the results of the release exercises group were more significant.
Conclusion: Six weeks of releasing and stretching techniques in non-specific chronic neck pain patients reduces pain and fatigue and increases their quality of life.
