Constant barrage of emails and requests from client
I have been working with a very nice client for the past several months. But, now, the contract is coming to a close. Just two more weeks. However, every day they are barraging me with dozens of emails and new requests. Now, they want a rubric for the course. Of course that would be helpful, but it was never part of the original contract, and never mentioned until now. Would you do the work anyway if you weren't paid? They also want other new work done such as a syllabus, and revisions they won't pay for.
What would you do? What would you say?
I don't think they do it out of malice, but out of genuine need, and I would like to work with them again. Unsure what to do.
