Hey Ujval,
First, the HR needs to rise above its orthodox functions of recruiting, training, etc. These are the expected job roles of any HR professional. HR practices would only be considered best if they enhance the productivity of the employees. For instance, you should ensure a quality work life for your employees. Find innovative ways to motivate the employees, such as awards, gifts, etc. Also, figure out ways to break the monotony of the workplace. For example, you can allocate two hours a day for a carrom competition. This will be a refreshing factor for your workforce.
It is also crucial that employees have faith in your HR policies. This is key to building loyal employees. Address their grievances to strengthen this trust. As mentioned earlier, apply for awards to benchmark your policies, etc. These efforts will help improve the quality of work life within the organization.
