First give the new joiners different contracts, then when the percentage of "new" contracts to "old" contracts are up get the HR guy to say that it is not acceptable that people have different contracts & all contracts must be brought into line. Then there are 2 choices:
1) Increase the "new" contracts leave or.
2) Decrease the "old" contracts leave.
What do you think?
After running multiple & extremely complex simulations with myriads of inputs & variables I believe that I have the conclusion....
Obviously they will pick the first option since HR is al about honesty & integrity.
On the ticket front HR are trying to arrange our travel by boat or train since the contract does not state that your transport is necessarily by air.
