Above The Law wrote a very thoughtful article today about how a lot of people in this industry get no bonuses at all, and specifically mentions paralegals and secretaries. They were tacitly chastising some of the associates who were bitching and moaning about how "low" their bonuses were. I was working on a post myself about how self-serving, petty and childish those complaints are, but ATL beat me to the punch. It's well worth a read, but don't venture into the comments section unless you want to get very, very angry.
Instead, I'll just end with a short note about my personal situation. An associate with my level of experience would be getting a bonus roughly equal to 15% of their annual salary. My bonus this year is a shade over 4% of my annual salary, and that's twice what I got at my last firm.
But I am NOT complaining about my bonus, in fact I'm happy to get anything extra at all. If anyone feels otherwise, I suggest you compare the definitions of "bonus" and "entitlement" in the dictionary, then smack yourself upside the head with a 2x4.
