If your helper breaks expensive stuff is it fair to deduct their salary? The helper broke a $2000 vase which I said to be careful

oh dear :( yea, i think it's fair to deduct so it lets her realise the importance of being mindful, especially if it's something so pricey. is this the first time she has broken something? talk to her and explain the rationale behind what you have in mind. as for the value to deduct, it's really up to you i guess... since their pay is not alot either...
