You completely changed the meaning.
Really? Tell me where I went wrong or how I changed the meaning of the sentence, so that I can learn.
I remember I did the following changes(numbered in red):
As I have reached 1 the end of my [STRIKE]6 [/STRIKE] six-month 2 contract period, I would be glad to hear your decision on whether [STRIKE]or not[/STRIKE]3 we 4 [STRIKE]will[/STRIKE] are allowed 5 to continue working [STRIKE]together [/STRIKE][STRIKE]in 2016 [/STRIKE] 6? "
1. I changed the past tense to present pefect as bhai did.
2. I hypenhated the word (as per Barb's comment) and changed the figure to word (which is recommended for single digit number, isn't it?)
3. "Or not" in "whether or not" is redundant.
4. I questioned why OP started the sentence with "I", then changed to "we".
5. I think this is the part you might have found misleading. Let me explain.
The sentence is about a person who has reached the end of his employment contract and wants to know (his employer's decision) whether the contract will be renewed. The renewal is subject to his employer's approval, in other words whether the his employer
would allow the contract to be renewed.
I believe this is a clearer and more straightforward way of saying "..whether or not we will continue..".
6. The issue of whether the person can continue working is current, so "in 2016" is understood. It does not make the sentence any clearer.
"Together" raises the question "together with whom"?
