Employment letter

Hi all, I am on work permit. I am about to complete a year of working in the same organization. My employer would provide me an employment letter but they are not willing to state that they will keep me employed for the next 1 year once I get the PR, but it’s a permanent job in an IT firm. Can I still get the 50 points in CRS score ? Is there any work around for this ? Any leads will be highly appreciated.
