Objective: Environmental awareness is defined as the level of people's information about environmental issues and the effective factors in its expansion and knowledge of how to behave to improve problems. The purpose of this research is to investigate the effect of environmental awareness on green human resource management with the mediating role of employees' green behaviors and green innovation and the moderation of servant leadership.
Methodology: The research is a descriptive survey in terms of practical purpose and in terms of data collection. The statistical population was 8000 employees of active petrochemical companies in South Pars region and the statistical sample was 370 people. Cronbach's alpha method was used to obtain the reliability of research variables. Partial least squares method (Smart pls) was used to measure the fit of the research conceptual model and hypotheses.
Research findings: The result of the research shows that environmental awareness has a significant effect on the green behavior of employees, green innovation and green human resource management. The green behavior of employees has a significant effect on the management of green human resources; But the effect of green innovation on green human resource management was not confirmed. The green behavior of employees plays a mediating role between green human resource management and environmental awareness; But the mediating role of green innovation and moderator of servant leadership between green human resource management and environmental awareness was not confirmed.
Research innovation:The investigated research helps the managers to put the process of selection, recruitment and green training on the agenda and to strengthen the awareness of human resources in the environmental field and by using the mediator role of green behavior of employees, green innovation and moderator of leadership. Servant, help to form an environment-friendly environment.

         The “Right to Strike”, as a fundamental right for demanding the legal claims of employees has maintained an important role in regulating the labour relations in the last decades. Importance of this fact, especially about the public sector servants with attention to organic sensitivity and function of this section, becomes multiple. Recognition of this legal phenomenon requires understanding the public sector servants, and illustrating the general approaches about recognition and regulation of this right. French approach is based on recognition and ensuring of this right about the mentioned servants with some restrictions and prohibitionsi, while English approach is based on denying the right natured of this right. With attention to legal vacuum of public sector servants’ right to strike in Iran, in this paper, we are going to investigate and analyze each of the mentioned approaches and theirs affects on regulating of the servants’ right to strike, and then select a dominant approach.

Asian sea bass (Lates calcarifer) an important marine species of high economic value and excellent meat quality, has suffered great losses due to disease in high-density aquaculture. The macroalgae, Gracilaria pygmaea, which include various bioactive compounds, may serve as an immunostimulant in the aquaculture industry. This study aimed to assess the effect of dietary fish meal replacement with Gracilaria pygmaea meal on immunity, activity of liver antioxidant enzymes, intestinal tissue, lysozyme gene activity, and IGF-I gene activity in Asian sea bass (Lates calcarifer). To this end, 120 individuals of Asian sea bass with an average weight of 28±0.5 g were divided into four treatments and three replicates and kept in 12 tanks (10 fish per 300-liter tank). Blends of soybean meal and fish meal were used as a Control diet (C). Experimental diets were prepared to substitute the fish meal with 3 (GL3), 6 (GL6), and 9% (GL9) of G. pygmaea in the basal diet. Fish were fed three times daily for six weeks. Dietary supplementation of G. pygmaea led to significantly increase in total immunoglobulin level compared to the control. The inclusion of G. pygmaea in the diet did not affect the antioxidant status of the fish. The histological analysis showed that fish of all groups exhibited normal morphology of anterior intestine and pyloric caeca. The obtained results showed that fish of GL9 and the control groups had the highest IGF-1 mRNA transcript abundance in the liver compared to the other groups. The changes of lysozyme expression noticed among the groups were statistically insignificant. Overall, the results obtained in this study indicated that dietary G. pygmaea did not cause adverse effects on immune status, antioxidant status, intestinal morphology, and lysozyme gene activity in Asian sea bass.
