Upset

My company was bought over and I mentioned it before.
Besides having to relocate physically, we have to be integrated into different teams in our parent company too.
As most of us have multiple roles now, it was extremely difficult to map us to new teams that were very functional.
I am doing sales support and is responsible for pre-sales, service delivery and post sales activities. For the longest time, they had no idea where to put me.
When they finally decide to put me to pre-sales....they do not know what I can continue to do under the new business structure.
When a new post came up....I was excited and thought its a fresh new start and so I jumped to the post sales team.
Apparently NOT.
Just found out that it's pretty much what I do now...with an expanded role.
What's worse...I have just found out I need to cover my colleague in Malaysia as well.
Atrocious...and I am quite upset.
I would rather stick to pre-sales if that is the case.
I need to find a new job. FAST.
