Therefore, if you started last summer and finished your 8 months between Jan-Apr this year you can not take any leave until the Autumn. Hence, why I said you are forced not to take leave for the first 16-18 months within the company (unless you call in sick or fatigued - both of which you do not get paid)
Surely this was written black on white in your contract, and surely you read it through before you signed it?
