Hi Archna,
Your approach is ok. However, the last one, "availing 2 CL, the 3rd will be LWP despite we are having enough EL in our a/c" is a bit harsh one. I would suggest you may revisit this stipulation, to be fairer. This stipulation, when implemented, shall render "7 days" as redundant, non-existant as one can't avail the 3rd CL. Which means effectively one can avail only two CL in a year?? May be you meant to say "3 days of CL continuosly" is't so?! Ofcourse, employees will have an option of applying straight EL, if & when they would have already availed 2 CL in a year (calendar year ??). But many units have their leave policy that CL and EL/PL cannot be combined, meaning 2 days of CL towed by few days of EL continuously. Which is not permissible.
