Of course the term "emotional labor" has a definition as do all terms that qualify as jargon. What makes the term in question ideological jargon is that it was invented by practitioners of an ideology (feminism) to refer to a concept that is part of the ideology.

My comment was responding to someone who was complaining because men do not take the voluntary initiative to plan and execute things like workplace birthday parties. If the boss assigned the task it would not involve taking voluntary initiative.

If the boss assigns the job to someone, that is different. Since I am a non-feminist, I would not regard having to perform an unwanted, extraneous task, like preparing a birthday party as "emotional labor." I would simply refer to it as "unpleasant."

Although, if the boss assigned me that kind of task and expected me to do it during my non-working hours, I might resist. As a result, I could be looking for a new job, but that is life. If I were expected to perform a task during non-working hours, I would expect to be paid overtime, or at least get compensatory time off.

In an individual case, a secretary might feel pressure to fetch the boss's coffee. Feminists have voiced a general objection to that practice. They have collectively pressured bosses to generally desist in that practice.

If I ran a company and I wanted my secretary to fetch coffee, I would include it in the job description.
