Follow your path (Score 1)

I've been there, I was outsourced to HP and this is what I saw:

1- Business as usual for about 2-3 years. Yes processes will change, you will be pissed off at certain things, but overall, HP managed well its new employees, both at the beginning and during the cost reduction phase.

2- People are usually unhappy because the service level changed (more often than not it deteriorates).

3- Outsourced people are unhappy because the peculiar business of a service provider is not to help the client as a member of the "client's corporate family" but to make money first while providing a service to the client. As such, initiatives are sometimes not welcomed, you have to go by the book; you are now providing a service and as such you must not do more then what the service level agreement stipulates. It can be very frustrating at times, especially when you were used to suggest ideas to improve things with your colleagues. They are no longer your colleagues, they are now employees of your client. You have to change your perspective: the target for your initiatives is now HP, not your former employee.

5- After about 2-3 years, cost reduction phase starts more aggressively: HP is there to make money and they will try to get rid of the "redundancies" (the said fashionable term changes pretty regular according to the management gout-du-jour). They will also try to "share" the good resources so it can be an opportunity to work for other clients: can be very interesting.

So basically, after the understandable denial phase of your grieve process, try to not resist the change and see what's there for you, what's part of your path.

Of course, in any case, dust off your resume.

Good luck!
