thank you for your interesting perspective. When you say run hugely successful businesses on their own, you mean they do the cleaning themselves? If so, isn't there a limit to what they can earn because there are a finite number of hours they can work and presumably a limit to how much they can charge per hour
Yes, and that's the "problem". They can only work as much as they can physically fit into their schedule, and they won't profit from others doing the work for them.
As for the limit on how much they charge (whether they are charging per hour, per day, half day, or per job, it doesn't matter), that all comes down to how good they are and how well they know their market. When I started my own service in the early 00s, I was quickly able to establish how much the "brand leader" from the franchise sector was charging their customers, and it was not an insignificant amount of money, let me tell you. I knew it was going to be high, as I knew how much they were paying staff, which was well over minimum wage.
What I wasn't expecting was for many of the clients I found (from leafleting their homes) to be telling me that it was almost irrelevant as to whether they paid more to a "business" as opposed to a person, because all they cared about was what they paid and what they got in return. A good, reliable, solo cleaner who cleans professionally as opposed to a side-line they're not really committed to can earn a respectable amount of money, because they'll always be able to offer a better service than one with staff. That's not to say businesses with staff are no good, of course it isn't, and a great many clients are happy to pay for that service, I'm just saying that anyone who's prepared to go at it alone can be well rewarded financially. Trouble is, it's a dead-end opportunity, so you have to take from it what you can. It's great if you only need a job, but it's not a career.
What I have never understood are the cleaners who work for a company -and more typically an agency- where they are expected to be self-employed. Cleaners in this situation are so, so very close to working for themselves and with few benefits of being an employee, that I don't understand why they would do it, unless of course they are so bad at cleaning or managing their clients that they don't dare to go at it alone. The agencies are the ones I understand the least, as what they tell the client to pay the cleaner can be a pittance.
On another note, there's no way I'd do the half of what I do for my clients if it was I worked for a company. I do it because I like working for them and because I can charge a respectable price. I'd hate to be going in and out of houses all week long, not knowing who lived there and if I'd ever be going back to it. There's no incentive to work hard at the cleaning if there's no knowing you'll go back to reap the reward of doing it well last time. And if you are a great cleaner, there's always the risk that you'll be the one that gets sent in to clean the homes where people have complained about low standards, only to find you are moved to another job just as soon as you've got it in some sort of order. This happened to me once when I was working in a hospital as a domestic - I never went to the same area more than two or three times, I kept getting put in areas where work was needed. I didn't realise at first what they were doing with me...but I soon caught on.
