I do find it quite confusing and also because I cannot budget then. I budget quite meticulously.
I tried to change the amount on their cheques a couple of times with their permission, but they didn't have time to initial over several days, so my payment ended up being quite late after they finally got around to it. I have no interest in hounding people day after day to initial the cheque.
After that I decided to remind them via email that I needed new cheques and if they did not get around to it, I still have a cheque to cash. I guess that is my way of putting their responsibility back in their court, and if they don't provide the new cheque they lose the reimbursement. Nothing tends to motivate people more than money.
I agree with not dealing with an adult I have to coddle. She has been here two years and it seems that in the past year she is getting more challenging in this way by the day. I think that this boundary I have set has put a bit of a jolt into things.
I set my holiday days, paid and unpaid on a document and email it out every November for the following year. I have an unpaid day set out for July, which she remembered to take off of her July cheque. Good to see she is getting it together a little bit.
