I think you are too harsh on the SM. It sounds like people in your complex are reluctant to be on the committee if The SM has to Encourage people to stand.
The alternative is that no one nominates and the SM automatically assumes all the roles.
I think that not a place any strata wants to be.
Take the initiative and become more engaged. That probably means establishing a working relationship with the SM. They generally help people who show an interest.
Also, take a strata course. I can’t mention any names of organisations who provide these, but there are courses for strata committee members. It’s pretty cheap.
