(((((((((Rebecca)))))))) Good to hear from you again but not so good to hear what has happened. I had a boss like that once; made me understand the reasons for unions. She's obvously got her own problems and she needs to get her own act together. Of course you KNOW you are not responsible for keeping her sinking ship afloat, but you have to feel that too, hon. There is only somethings you can do when the other isn't willing to take the steps to meet you halfway.
Hang in there, dear. You can handle this semseter, even though it has started so roughly. HUGGGGSSSSS and welcome back across the pond.
