What is upwork doing to protect the freelancer for false job feedback, where generally after completing the work and getting work submitted. the project owner gives false feedback or demands full refund of money in exchange ... this is a serious problem on upwork...
" ... inexperienced clients demand insane things like a total shift in requirements with no additional billing, or they underestimate completion times when they have zero knowledge of your trade... all while holding your profile score hostage when you try to reject in reasonable ways... Upwork throws up their hands and says they won't intervene..."
I agree with that almost entirely. Upwork does have some lesser observed services that I didn't even know about that help stand up for the client (and I don't mean arbitration).
But changing the grounds of the deliverables from either end shouldn't be tolerated and should also be obvious. That's why I build in milestones...it helps to self-check that the work being submitted is acceptable (granted not always possible to do.). I also make a habit of spelling out exactly what I'll be doing.
More work on my end, but less taxing on the psyche.
