Management seems disorganized, and there are many inconsistencies in their policies. Their expectations are not clearly communicated and seem to change often. Some policies are only communicated in the Slack channel and not recorded in official documents on the website. There is an air of unprofessionalism here.
The write-up for the client takes extra time that cuts into your overall pay, and the guidelines for writing them are confusing. While these kinds of write-ups are standard in copyediting, the pay usually reflects the time required to write them.
Clients are discouraged from but still allowed to input files in PDF and Latex format, which many editors are not equipped to handle. Editing these kinds of files is also much more time consuming even if you own the required programs. These are supposed to be clearly flagged in the system but they are sometimes not. If a file needs to be converted, the editor is responsible for doing so, which wastes time.
There should really be a rule that clients must always submit Word documents. I get the impression CP just doesn't want to turn away clients or risk losing their business, even if this is detrimental to editors.
Email communication with management is usually good, but you may get different answers from different people. You sometimes don't receive a response at all during busy times.
The online system is not very user friendly and should really be updated.
There are other companies with a similar business model that put a lot of effort into taking care of their editors and helping them maximize their earnings, which in turn means high quality edits for their clients. CP pales in comparison, honestly.
