As business owner, let me be frank. Its almost impossible to hire someone above 50 because of the following:
1. Most old people can't cope with technology. Some so stubborn, die2 want to use old school system.
2. Health Issue.
3. Attitude. Old people are usually stubborn af. They dont want to listen to young people, no matter how good the advise is.
4. Salary too high mainly because years and years of experience. But let face it, 10 years experience is good enough already.
5. Commitment issue. Young couples, or newly married couple are better as they have commitment. Old people usually have this dgaf attitude.

I know it does not apply to all, but most are. I do have one manager at 56 years old. Dont know how to use phone other than forwarding message and tiktok. Cant even use online banking. Stubborn af. Had bypass surgery, slip disk, and yet still smoke like no tomorrow, everyday also drink cap kapak whisky.

I know Power BI, who says I old school system.
Health? my blood pressure is 110/75. I cycle 75km a week.
Attitude. Well I am doing a different role within my co with same pay.
Commitment? I have commitment. My kids still young.

I hope you drop fallacy about old staff mentality, not all of us are useless.

I literally says at the end of my reply there, not all, but mostly are. And u tend to ignore that and continue to justify. No one says anyting about being useless. Its arrogance, and it shows here.

No one talked about old school. I am talking about adaptability to modern system. Knowing stuff and being able to adapt to it are totally different things.
Health is not just about blood pressure. And 75km per week is low, especially cycling. Cycling does not put much pressure on your knees. When u are old, a lot of disease lurked in without u knowing. When is the last time u did full medical checkup for 50 and above? Not just normal medical checkup, but special one for people above 50.
Attitude is not about doing different things or different role. Its about how u treat other, especially people who are younger than u. Its about how u swallow your pride, and being able to listen to younger people advise.

Your replies shows how u see younger people.

And since you have experience, why dont u do freelance? Since u are in accounting, I know a lot of companies looking for freelance to do their management account and audit account.
