I recently was hired on as a contract temp at a company to do web design. When I arrived, my team consisted of a full-time employee of the company and another temp who'd been there for about 3 months.
We both worked hard and busted our tails for the company, but someone higher up must've liked me because after about 3 months, I was strongly encouraged to apply for the same job with the company. I did immediately and after a week, I was offered a full time job, which I accepted immediately.
Soon after, I realized that WE weren't being hired on, I was. I didn't think I was too far ahead of the other guy, and in fact I think we're even. That's not my problem.
My problem is that I start full-time in one week and no one has told him. This is important because I'll have to go through a 2 day orientation at the same time that our other team member AND manager are on leave/PTO, leaving him to do 3 people's work with no backup for two days (We primarily field questions from our clients about fixing sites we've done). This is on top of him being leapfrogged for a full-time position.
What's the best course of action for me in the face of this? I'm definitely waiting for our senior manager (manager of my manager) to announce my hiring I don't want him to become bitter or spiteful at me due to circumstances outside my control. Things have a potential to get really awkward due to us working immediately next to each other, as well as me being very social and well-liked among our coworkers in other departments, which could lead to things like random congrats at my desk when he's around.
I don't really know the guy, but I also have to deal with him on my team for as long as our manager and coworker are on leave. We have a cordial work relationship, joke around, and have went out for drinks with our other coworkers.
Basically, how do I act in this situation that keeps our working relationship intact?
