Purpose: This empirical study aims to determine the effects of a toxic workplace environment, which can negatively impact the job productivity of an employee. Methodology: Three hundred questionnaires were randomly distributed among the staff members of seven private universities in Pakistan with a final response rate of 89%. For analysis purposes, AMOS 22 was used to study the direct and indirect effects of the toxic workplace environment on job productivity. Confirmatory Factor Analysis (CFA) was conducted to ensure the convergent and discriminant validity of the factors, while the Hayes mediation approach was used to verify the mediating role of job burnout between the four dimensions of toxic workplace environment and job productivity. A toxic workplace with multiple dimensions, such as workplace ostracism, workplace incivility, workplace harassment, and workplace bullying, was used in this study. Findings: By using the multiple statistical tools and techniques, it has been proven that ostracism, incivility, harassment, and bullying have direct negative significant effects on job productivity, while job burnout was shown to be a statistical significant mediator between the dimensions of a toxic workplace environment and job productivity. Finally, we concluded that organizations need to eradicate the factors of toxic workplace environments to ensure their prosperity and success. Practical Implications: This study encourages managers, leaders, and top management to adopt appropriate policies for enhancing employees’ productivity. Limitations: This study was conducted by using a cross-sectional research design. Future research aims to expand the study by using a longitudinal research design.

The current research explores the injection of a viscous fluid through a moving flat plate with a transverse uniform magneto-hydrodynamic (MHD) flow field to reduce sliding drag. Two cases of velocity slip between the slider and the ground are studied: a long slider and a circular slider. Solving the porous slider problem is applicable to fluid-cushioned porous sliders, which are useful in reducing the frictional resistance of moving bodies. By using a similarity transformation, three dimensional Navier–Stokes equations are converted into coupled nonlinear ordinary differential equations. The resulting nonlinear boundary value problem was solved analytically using the homotopy analysis method (HAM). The HAM provided a fast convergent series solution, showing that this method is efficient, accurate, and has many advantages over the other existing methods. Solutions were obtained for the different values of Reynolds numbers (R), velocity slip, and magnetic fields. It was found that surface slip and Reynolds number had substantial influence on the lift and drag of the long and the circular sliders. Moreover, the effects of the applied magnetic field on the velocity components, load-carrying capacity, and friction force are discussed in detail with the aid of graphs and tables.

Purpose: This article aims to illustrate that stress is not always a negative experience as it can have both positive and negative outcomes. The term “eustress” describes positive stress, while the term “distress” describes negative stress. To date, research on eustress is in the infancy stage. There are approximately 306 items that can be found in the Web of Science core collection for “eustress”, while there are 184,714 items found for “distress”. Few studies have examined the relationship between presenteeism, stress, and innovative behavior. Thus, the mechanism underlying this pathway still needs to be fully understood. Materials and Methods: A survey was conducted among 350 medical healthcare professionals from Pakistan. With the help of SPSS and AMOS, the data were analyzed and the combined effects of the variables were also investigated. Results: According to the current study, a mediation effect has been observed between innovative behavior and stress (eustress and distress). However, supervisor support moderates the relationship between stress and presenteeism and, likewise, between presenteeism and innovative behavior. Conclusion: Our analysis of variables establishes empirically robust relationships between the innovative behavior of medical healthcare professionals and the two different dimensions of stress. In addition, it describes a hypothetical alternative situation that explains how employees’ innovative work behavior is affected by eustress and distress in the presence of supervisor support. This study could have implications for improving medical healthcare professionals’ ability to incorporate innovative behavior into their practice in an effective manner in the future.
