I am not sure about the form of the verb that follows "neither". Should it be a singular or plural verb?
For example:
Admittedly, being a celebrity is not easy, but neither are being many other professionals who, unfortunately, receive much less compensation.
P.S. I came across another sentence on the Internet that says "Being single is not easy, but neither is being married." Here, the verb following "neither" is singular. So, may I ask what is the rule here?
The problem in your example is one of logic and congruence -
...neither are being many other professionals...
doesn't work, because the subject is a singular second person state of being. However,
...neither is being many other professionals...
doesn't work either, because (unless you're a New Age spiritualist) a singular state of being cannot transform mid-sentence into a plural state of being.
The solution is to rephrase. Use something like
...the job of a celebrity is not easy, but neither are the jobs of many other professionals...
or
...being a celebrity is not easy, but neither is being another type of professional who, unfortunately, receives much less compensation.
Either of these would be much more logical and congruent than your example.
