My partner, who is a vet nurse, got fired on Friday

. She spent 15 years of loyal service at her job in a casual role. New owners took over almost 3 years ago while she was on maternity leave and since her return it hasn't been the same.
Her Performance Reviews always were glowing about how well she treated staff and the clients (the animals). But a new practise manager came onboard 6 months ago. They tried pressuring her into taking training and racking up a $10-12K bill to do so because they wanted qualifications of their own for the business, but the timeframes and the amounts didn't add up. After staunchly refusing to sign anything without definitive timeframes, repayments and costs, all was quiet until they called her into a meeting Friday after lunch, terminated her position, and refused to give her an answer why and then escorted her out the door like a criminal.
This was her dream job and the new owners (who we thought were friends) treated her with such disrespect. The main business owner, whose animals we cared for, whose practise we helped renovate, whose wedding we went to, whose horse we helped put to sleep when it was sick, wasn't even there to do it face to face.
I was so mad, I went ahead and bought some Siege Micromasters even though i couldn't afford them as therapy.
