2) This was also discussed earlier, however there is no hard and fast rule as to the minimum %age of increment to be given to employees. However generally the %age of increment could be what is followed in such line of business and such of sister concerns. It will also depend on the basic structure of salary for e.g. there are some firms follow CTC pattern some firm increment on basic pay, some on overall %age of gross salary etc. Some firms grant just like that lump sum increment for exceptionally performing employees some times 20 to 30% jump also seen. For some under performers there wouldn't be any increment at all or withheld/deferred. A fair rate could be 10 to 15% p.a. on Basic pay is reasonable.
3) The leave matter was also discussed recently. However use the attached article to know it better.
