Oh I really feel for you 4getmenot. I work with the boss's daughter.
I have 20 days holiday a year- She has whatever she wants (so far 22 days this year)
I make all my appointments outside of work ie doctors, hospital - She makes her appointments in company time.
I have my hair done at weekends - She has hers done in company time.
She works less hours -I work more hours (She did work the same hours as me but decided to now reduce them, without taking a pay cut)
She earns more than me and her Mum! -I don't
She leaves the office as and when she likes for whatever reason - I don't
I work hard - She doesn't.
The boss thinks the sun shines out of her a**e - but not mine.
If anything goes wrong, I get the blame. She doesn't.
The stress this has caused me over the years is profound. It has only been in the last year where I have to accept this as I need a job. I have bills to pay and a mortgage. I have no choice. I do my work, I come home, I try to forget.
It's hard, really hard.
