The definition of "Extracurricular":

not falling within the scope of a regular curriculum; specifically: of or relating to officially or semiofficially approved and usually organized student activities (as athletics) connected with school and usually carrying no academic credit

The word I'm looking for might have this definition:

not falling within the scope of a regular work life; specifically: of or relating to organized activities unassociated with the company one works for

Essentially, non-work hobbies that one has during the period of life when a person holds a job and is no longer in school. I understand that "extracurricular" can be used outside of a curricular context, but it seems to be a stretch of the word.

A Google search reveals a single forced usage of the hyphenated word "extra-career". This is more or less what I'm going for.

Example sentence:

Thomas, you need to get involved in some [non-work related] activities if you want to meet people.

I opine that extraprofessional is as close as you are going to get to extracurricular. Both are formed using the same prefixes appended to adjectives for what you are describing. The word is found in both the 1896 printing of the Century Dictionary and Cyclopedia (C.D.C.) and the 1913 printing of Webster's Revised Unabridged Dictionary. The C.D.C. entry for the word is this:

Extraprofessional ([…]) a. Not included within in the ordinary professional interests or duty.

 Molina was an ecclesiastic, and these studies were extraprofessional.  Med. Repos.

Naturally, I consider extraprofessional an apt substitute for extra-career since professional is the adjectival form of profession, and profession is considered a synonym of career by Roget's 21st century Thesaurus. The reason I am preferring an adjectival form is because curricular is the adjectival form of the noun curriculum according to the American Heritage Dictionary 5th edition, and I suspect the reason extra-career seems forced is because it's probably being parsed as a noun.

Although I could not find a more recent dictionary with the word, I believe it is a morphologically obvious construction, as both use the same prefix applied to frequently used adjectives and Google Ngrams seems to indicate that the word was used with increasing frequency up until the late 1970s, and despite declining usage, it seems to be at least as popular today as it was around the turn of the 20th century:

For an adjective similar to extra-curricular, you should check recreational.

Thomas, you need to get involved in some recreational activities if you want
to meet people your age.

If a noun is acceptable, you may use hobbies/pastimes.

Thomas, you need to get involved in some hobbies/pastimes if you want
to meet people your age.

ODO:

recreational
ADJECTIVE

1 Relating to or denoting activity done for enjoyment when one is not working.

1 An activity done regularly in one's leisure time for pleasure.

‘her hobbies are reading and gardening’

pastime

work; a hobby.

‘his favorite pastimes were shooting and golf’

Avocational is the adjective for avocation:

a hobby or minor occupation.

Compare with vocation:

a person's employment or main occupation.

Both definitions are NOAD.

so if a guy sold weed on the side of being a dentist that would be a extra profession

I agree, but have to argue with how it (extraprofessional) could -but only- "appear" compatible as it would least apply to an exhaustive level of application/usage.

For instance, I am in need of the word in question to address a short professional narrative to a recruiter, where I want to state that I'm rather "cynical" about asking my "current-employer" for a letter that states my 'career level' at his Company.

(Because of course, my "search" for a better position is typically,
inevitably -clandestine; well not exactly, so let's just say
-surreptitious, if you know what I mean.)

But coming to the point, in the letter I wanted to write:

    Absolutely Ma’am. I hope to be able to furnish it by eod tomorrow.



    Further, as I'm afraid, my current employer wouldn't appreciate my extra-()

...

The "()" marks the place where I found myself stuck.

However, I intended to say:

Further, as I'm afraid, my current employer wouldn't appreciate my extra-(curricular/professional - such as "sneaking around job-hunting")-activities,  to any degree, I am unequivocally doubtful about my being able to furnish...

(I just got an idea, my "problem" (not this 'topic') solved itself haha! Anyway,-)

Therefore, as I think "extraprofessional" does not suit my scenario, unfortunately, which is by all means an applcation that denotes "Profession(al") but outside the scope of a... uh legitimate/registered career/profession perhaps.

Is there no such word that denotes "job-hunting"-(extra)~professional?

But "extraprofessional" does seem to work for "non-work"-related activities -boozing after hours for instance, so yes it could have been only a subjective word from the past.
