There are very few (can't think of any) other self-employed jobs like ours. We are limited in how much we can earn. To operate legally, there is a maximum number of "clients" we can have. If I had a store, I would only be limited by the the amount I could sell. I could have 1 client per day or 1000. I could charge as much as people were willing to pay. If I cleaned houses, I would only be limited by the hours in the day. This is not to say I could earn a million dollars doing either of these things, but they are different from home daycare.
Here, we are further limited by the law. I can have a max. of 6 clients and work a max of 236 days in the year and the pay is predetermined. For this reason, we get paid for 8 stats and for 17 days vacation.
In the rest of the country, I imagine it is more about what clients are willing to pay in any given area, but I don't think it is unreasonable to expect paid time off.
As a self-employed person, you are not entitled to most of the same "social protections" as employees. EI for example, (you can opt-in but then you can never opt-out.) And workman's comp. And maternity leave, and a pension plan and a group health plan. These things are not available to all employees everywhere but they are to many. None of the home daycare providers get them (except in Que.) So some compensation and some time off, again, not so unreasonable.
