I work at a moderate-sized office building (400+) which is part of a larger corporation (150k+). This morning we were given instructions on what to do during today's tornado drill. At the end of the email it said, "Your participation is required but not mandatory."
Does this mean something I don't understand? I don't know this person well and would not want to ask them, mainly because it would indicate that I don't really want to participate if I don't have to.
UPDATE I ended up just following the lead of others on my floor, which was just to continue work (pretty typical for my office). My guess is the person meant to say "requested" not "required".
