I am in an IT graduate program in Western Europe for a big company where I am supposed to rotate only once a year. I am working there for four months but stuck in a rotation with nearly no work for two months.
The IT project I am working on, called Project A, is being replaced by another one, called Project B; the official announcement has been made two months after I started here. Therefore, there is nearly no work to do in my team, most of my team has been either transferred to Project B or fired. For two months, I am only busy around 10% of the time because nearly all the tasks have been cancelled and we don't have the budget to create new subprojects.
I have been approached by a manager of Project B who would like to pull me into his team, which seems very interesting. However, my manager of Project A refuses this internal transfer because he believes that in the future he will be able to restart the project in another division of our company. Therefore, in the meantime, I am supposed to wait and nearly do nothing instead of joining a new exciting project. HR have been contacted, but they are not motivated to act because my manager told them that Project A is going to be restarted, even though no progress have been made in the past two months and there is no evidence of a possible restart.
How can I get out of this situation? I feel that my manager refuses to transfer me for political reason and HR refuses to go over the head of my manager because I might have a lot of responsibilities if the project restart.
Last update is that HR asks me to schedule a meeting with them and my manager, but I don't know how to approach this meeting without being too rude in front of my manager and HR. If I run this meeting and the transfer fails, the remaining 8 months will be long.
