I'm sorry. That totally sucks. I know the feeling. Not the same situation but my boss thinks 'yous' is a word and I just can't. Also 'yous guys.' Huh, do what now? It's so unprofessional. She cannot compose an email without asking me to proof read it. She's just not bright. It sucks. I'm not the smartest or even close to it but grammar/the English language....we're in our 40s. I would think she may have mastered that by now. Yikes...I'm getting mean....I shall stop bc I like her and she has a good heart. :)
I hope things get better for you.
