Hello - looking for some guidance. We've had a lady doing our cleaning once a week for the last 3 years. Generally reliable until the last few months, but then sending last minute cancellations, and not doing quite as thorough job as previously. I don't want to make an issue out of it, but am going to let her go, as I'm doing more and more myself each week anyway. What would you consider to be a reasonable notice period? I was thinking 4 weeks? No contract, etc to refer to so a bit stumped as to what is best practise.
