Well, the language reads "no earlier than after one (1) year of active employment", which is somewhat vague and could be interpreted in a couple of different ways. The fact that you were seasonal and then kept on after peak makes it more unclear. I am not an expert on the contract, maybe someone else might have a better idea.
I can say for sure unfortunately you will not receive pay for next Monday, but I am not sure how it will work out for the 5 holidays at the end of the year.
