Gentlemen,
Please note that if you do not take your 50 days leave you are not entitled to the 2 travel days. i.e you are entitled to 1 travel day per block of 25 days taken. Is this allocation of 25 days just a step to pre-empt the fact that you may not take your leave or have it cancelled any way?
May be HR has not terminated the 2 days but will tag it on once the 50 days are taken in 2 separate blocks. If you take only 1 slot or part thereof you are only entitled to one extra day.
