Personally, I think they're just not go-getters (your
co-workers).
Thing is, there's systems within systems.
I've had complacent co-workers. I wasn't one of them. I had my
own agenda that I allowed to match up with the authorities when
it suited me.
Was I fooling myself? No.
I crossed departmental lines to help people outside my
department, even competing departments because MY AGENDA was to
assist people to Betterment; whatever it was. [in that case, it
was helping them get to a point where they could use Excel and
other data tools to do their own reports, be better at their
jobs, and help the organization as a whole... but mostly.. to
help them as people.
Someday they may leave that job.
Their skillset remains.
I helped.
Some people's mission is just "get through the day because there
is a beer waiting at home." And that's fine. Everybody has
goals, even if they're unspoken.
