Hello Careerlanders. I need advice on this topic

About a year ago, my Dad died, being an owner of a primary school with my mom, thereafter o assumed head of the school, although I run my own freelance engineering installation and maintenance service on HVACs and Diesel engines.

In course of this education line, I'm obtaining my certificate in PGDE( in view).

Now this is the case...

There are some old staff in the school then whom use to collect school fees on behalf of the school and you know Nigerians, instead of remitting the fees to the school, they divert and scam and even go as far as lending money to different people in the vicinity.

However since I took over, I forcefully stopped the collection, and redirected all fees to be paid at the bank. Mhen, it was not small trouble, fight, gossiping, spoiling me at the back etc, but I never listened to such, and right now no one collects these fees again... Everything goes through me coz I'm trying to sanitize it. I also required the services of a registered security company operator (sheriff deputies) for the school

Problems I needed advice

1. Sometimes these rebellion. They gossip and talk evil to people that I'm very harsh etc

2. I have changed 2 security operators because of compromises with these staff. I will give instruction, Buh those they'd do otherwise and bend to what other older staff tell them. Recently, the present security did something contrary and I scolded him toughly. Recently, he had an alteration with a parent and I asked him to just plead with her. He refused blatantly. I was surprised and even my mom too. He said he doesn't like the way I scold him and that's why bla bla bla, infront of all other staff. My mom asked me not to change him Buh I'm skeptical

I already feel like changing him with his company supervisor coz he lives around the vicinity and he now gossips with those old staff who might be telling him I'm too young to order him to do things

4. These old staffs are like friends to my mom and they already carry a lot of influence with most of the parents (which I also cut off too). One of them is wife to my mom's brother

5. My mother has been telling me to be patient even my wife. I do not want to employ an headteacher until I change a lot of things

The school has about 300-350 pupils, and employs 18 staff
