Student or Learner
I am wondering if the following passage is correct or not.
I would like to encash my 15days earned leaves out 30days. It is our company's policy that no one can accumulate 30dats earned leaves on his credit. so please encash my 15days leave to maintain 15 days on my account. your early approval in this connection will be appreciated.
It's not correct. You haven't left a space between the numbers and the word "days" each time. It's not "15days". It's "15 days". Your final sentence needs to start with a capital letter. Change those and then we'll look at the content.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
