I've recently got a new cleaner and although I've never personally met her as I'm always at work, she's very sweet and I know her business is struggling and she only charges me £13 an hour rather than £16 like most cleaner. Her marketing on social media is pretty naff and I've had years of experience working in marketing. I feel like I would like to offer help doing some of her socials in my spare time. I just feel it would be for a good cause. Would this be insulting to her? Abs how do I approach it?!
