You are right, I have asked before - it's hard to keep up, and we are very anxious not to exploit someone who we trust absolutely and who does an excellent job. We have decided to go for £65 for 3.5 hours. We pay when we are away, whether she comes or not, but not if she chooses to take time off. And we also do 2 weeks bonus, and paid throughout the lockdown when she couldn't come. Given what's coming down the track we think it's really important, if one can afford to, to err on the side of being generous so we'll be keeping it under review - expect more queries!
