We are fortunate to have a good Strata Manager, although their role is primarily legal and accounting and the AGM. EGMs and day to day are handled by our Strata Committee.
I would certainly concur with a single attempt, in writing so there is an indisputable record of exchange, of specifying occurrences of dissatisfaction, with a ‘fix-by date’, either by a new manager (if the company is big enough to have more than 1) or a reformed existing manager.
If that doesn’t solve the problem, I’d get out the firelighters and stack them under the bridge.
No strata needs a roadblock strata manager. They are paid to be professional and to do without reminding the job the strata employs them to do.
Past forums have provided numerous contact details of good managers, often with multiple endorsements for individuals.
