Finding good maids has always been a struggle. I've been living and working in BA for 22 years and I formally owned the largest property management company in Argentina. We had a good process for hiring maids. Had to pay them great salaries (in white), I was paying healthcare benefits for them once they were working for me for a year. Fortunate to have had about 20 maids.
But now I just have a few properties and just use the maid from the property management company. But they tell me it's not easy to find maids.
I think this problem is going on all over the world. I'm here in San Diego and although I live in the Northern suburbs, we are not far from Mexico so you'd think there would be tons of maids available but after COVID it's been extremely tough to find maids. The cleaning companies are terrible and individual maids are difficult to find. We had a regular maid for many years then she flaked out during COVID and now we just use a few but they aren't too good and it's expensive.
In Mexico, my friends report having the same exact problem. I'm not sure what the issue is but in Guadalajara where I own several properties and have many friends, they are all saying they are having the same problem. Many that had dependable maids for years have had them flake out or stop working.
