Unless you're in some office settings (with dingy bossie's) and then it's twice a month.
I had to fight this in my previous position - constantly - with everyone from the Director down to the front line manager. Guess here in AL, and specifically that business, bi means twice and therefore bi-weekly was twice a week, bi-monthly was twice a month, etc. I sure hope none of them try to get a job elsewhere that's bi-annual, or they'll be broke before they get a chance to say "bye".
