I have put a tender for external suppliers to provide cleaning services for my building and conduct a monthly fire inspection. All suppliers are required to put through applications and submissions why they are preferred supplier and I am required to make decision to whom:
[1 decision] - outsource the cleaning job
[2nd decision] to decide who will give the job for the monthly fire inspections.
At the end of the process, I am required to issue reasons for our decisions or reasons for decision to all suppliers who do not win the jobs.
[Assuming i have to write more that one reasons and it comprised of two decisions, one the cleaning and second the monthly fire inspection]
Which one is grammatically correct "reasons for our decisions or reasons for decision? Thanks
