Just get rid of the manager .. it sounds like he isn't doing his employer (the OC) any favors. Look at his agreement, read the termination clause and apply it at the appropriate time.
Strata owners need to get serious about the performance of their managers. Management is a boom industry and there are plenty of good operators if an OC is not happy with the one they have – better still you might consider bringing financial matters back “in house” if you can find a few people with a bit of commitment – could be worth a nice honorarium at the following AGM if they do a good job.
If you aren't a big SP and you do not do a lot of financail transactions and people pay their levies on time then it isn't hard to self manage. Some strata firm even offer DIY management packages with support – if needed.
Is it time people stopped complaining about poor managers and started replacing them. Get pro active and do your OC and the whole strata industry a favor and ditch the poor manager .. everybody wins (except the poor managers)
