I've been repeatedly learning a lesson about working in-house: don't let your clients bully you. This is difficult because attorneys want to make their clients happy; even in-house, where your "clients" are other people at your company.
For example, I had a program manager (an engineer) insist that we have the rights to use this code in a new Solaris build. I had to dredge up the agreement and review it while fending off the barrage of emails telling me they needed this approval today because it was mission critical to a pending release. I was frantically emailing up the chain to get confirmation of our licensing rights, as the agreement the client provided wasn't a solid strike.
Finally I got on the phone with a senior attorney, who praised me for flagging it and calmed me down. She reminded me that if the release was delayed a day, it wasn't the end of the world. This isn't the first time I've gotten worked up because of clients trying to rush my approval. Part of it is inexperience - I assume that the clients must know better, because I haven't been here that long. There's a lot of pressure not to get in the way of a deal. But there's a balance between business and legal interests, and the reality is that sometimes, doing your job means being a roadblock.
