That all makes perfect sense, Lorraine, but what if no one wants to take the job(s)? I've been told that most strata management agreements include a clause the nominates the SM to act in the office-bearers' roles in the absence of an EC member willing or able to do so. Of course, this costs money – they won't do extra work for free.
Maybe the answer for any building that doesn't have volunteers for office-bearer roles or a strata manager, is to get one.
