Apparently Dsis thinks I am so I would like some opinions of how to go forward from here.
Dsis has 2 children, one just started reception on just started year 1. She found out a few days before she was due to leave for a holiday of several weeks that she got accepted for a job, she called me and explained the job was 3 days a week but one of these days her CM takes off so BIL would collect the children on this day as he is a postman and finishes in time for school pick up. She asked me if I could look after DNs for this particular week day for SOME of the holidays.
She explained that her friend had said she could do a couple of days for her and she would use holiday leave for the rest of the CMs day off and CM holidays (1 week @ christmas,1 week Easter and 2 weeks at end of summer). I agreed to pick up SOME of the days for her, we didn't go in depth about it and she left for her holiday and only returned last week.
It transpires that she 'has me down' for 1 day in oct half term plus a non pupil day immediately after, and 4 days over Xmas hols (3 of the week day which i had said i would cover SOME and one additional week day), she then asked if I would like feb half term dates and can I let her know with in the week. I asked about her friend, apparently she can only help at Easter.
Her husband has used most of his holiday for this year and what he has left is booked and cannot be changed. He apparently can't take time off in Dec anyway but managed to get 3 weeks off unpaid leave last dec to go to Aus for cricket . She said he has to do his holiday form at the end of April for the coming year and that as holiday has to be book in week blocks and is unlikely he will get it for the school holidays as it is over requested.
^Does anyone know if this is true^
I wasn't expecting to be doing ALL of the holiday cover for this day as that isn't what she said when i agreed. Yes I should have checked in more detail when I agreed but I took it as what she said--SOME.
Now I wouldn't really mind too much if I needed to cover all the days until they can sort out both of the holiday leave in April and then I wouldn't be needed to cover or only provide a few days but I am almost sure that BIL who is a lazy, emotionally abusive, financially abusive twat of a man child, won't book his holidays to fit school holidays so it will be down to me and my sister.
Also just to point out (so to give the full picture), Dsis has MS, she was working when diagnosed and tried to return to work several times but her health suffered as she was still responsible for all house and child jobs so she quit to focus on her health. this will be her first job in around 15-17 months.
The biggest reason i agreed was that she regularly has no money left 2-3 weeks into the month but her husband does, she has to spend on credit cards to meet her and DNs needs and just pay the min every month. I believe from small things she has said that she is nearing her limits and in a bit of a mess. BIL won't give her money, he has expensive hobbies which are more important than say kids clothing. I wanted to try and help my sister out so she could become more financially secure.
I have a 3 year old so would be looking after her and a 4 and 5 year old. Yes I am sure it won't kill me but it won't be a walk in the park either.
I want to just hand her a list of when I can do, was thinking one day oct half term, 2 days xmas hols one day either feb/may half term and 2 or 3 days in the summer (always go away at Easter). I don't think that would go down well though.
AIBU to just give her said list/refuse some of the days she has me down for? How can I not piss her off and cause damage to our relationship?
