I'm experiencing the same problem, with both the gardener and maid. They showed up one time, after I hired them, but never again. I only have one household member and no lot traits active. I've tried cancelling the services and rehiring them, but they have not appeared at my lot again, since that first time.
Vigilos Are you using mods/cc ? They do not come on the weekend but should then show up again on Monday.
Thank you, crinrict. I do have some mods, but nothing that I think would interfere with the hired services, and I haven't changed the max character count for my lot. I ended up giving up on the core game hired services and instead installed a mod for live-in services. That has been working well so far.
