Dear Jyoti madam.
Before even thinking of change in employee service conditions of peripheral nature like 5day week working or increase in leave, you need to make thorough homework/ground work on core aspects of business.
Firstly, understand thoughrly the vital aspects of your business processes, from product manufacturing to reaching the customer, cost of doing it and profitability and deliverables to customer.
Understand the competition, the service conditions of employees, performance standards and total picture of what gives competitive advantage/edge.
Based on the total picture, pick the most important area of change ie, remuneration, productivity improvement related incentives , leaves, fringe benefits.etc.
Remember , no management will support any improvement in the employment conditions, barring statutory required, which are not likely to improve work efficiency, productivity or any other advantage immediately or in the long run. It is sheer a matter of give and take.
