This is what you said at the outset.
I have to stay on for a week or two until my testimony as an expert in an on-going trial is completed.
.
In response to comments you said:
A Declaration of Expert Witness was filed a long time ago and the attorneys would have to refile a substitution, which I guess would delay things even more for a new discovery phase on the expert substitution.
And the problem is yours?
But you also said:
My boss didn't even ask about the trial. He had assumed it settled. He wasn't at our last biweekly staff meeting where I gave a report on where my ongoing cases stood.
So, let me get this right.
You were called in and told you were canned.
Did they give it to you in writing with a declaration of when you were to be gone by?
Did they then say "Clear your desk, you can go home today but just hand over any outstanding work to someone."?
It seems your boss was not aware of any court work. I have to assume he wasn't saying, "You are canned but we expect you to work your notice period." I mean, how many companies do that?
So, the next bit is presumably where you say "But I've got this case coming up."
And the boss says, "fine, you'd better hang on till that's completed."?
The reality is the boss should, having made a decision, acted immediately on it and then dealt with any issues in a fair and decent manner, not just exploited your good nature and he should have allowed you some time to think about the situation as he himself should have done.
Fair means either bringing you back on contract at appropriate rates where you control your spare time or it means requesting you allow them to rescind your notice until the case is over but agreeing a guaranteed separation bonus.
Once you had that notice, you were history.
So do you now have a new notice to quite but with lots of ifs and buts in it to cater for the trial?
Have they made any gesture toward you?
