Actually, the proper way to say the sentence is as follows:

You actually do some work, as opposed to me, who just pushes paper.

The sentence would not use the word “myself” as a reflexive. The reflexive “myself” requires you to use the word “I.” Clearly the sentence uses “me” and not “I.” As far as the comma goes, to some degree its usage is a matter of preference and style.

“…as opposed to myself, who just pushes paper.”

“you actually do some work, as opposed to me, who just pushes paper.”
–or–
“you actually do some work, as opposed to i, who just pushes paper.”

and it gets a little more confusing depending upon whether you consider w/ or w/o the comma.

“you actually do some work, as opposed to me who just pushes paper.”

general rule of thumb is “me” after a preposition (in this case “to”), but it’s falling apart.

any thoughts? gavin
