It's still a "market" so long as there are supply and demand, regardless of how frequently a given participant is conducting transactions in that market.

The housing market is probably a good example. Many participants probably only purchase property once or twice in their lives (less even if you consider the case of a married couple buying a house, that's 0.5 purchases per person).

I've worked for three different employers and have never left this spare bedroom. Relocate? Where? To my living room? :-)

Unless you live in a communist country, you are part of a labor market.

I don't think there are any purely communist economies operating in the world today, and even if there are, there is still a market. It's a badly distorted market that performs poorly, but a market nonetheless. If you have human beings involved, there's a market; it goes with the territory as part of the human condition.

Workers coops are neither labor market nor necessarily communists. If everyone democratically operates the company and shares equally in profits, there's no wage labor being performed.

Among many offers, I chose a company on absolutes, not relatives. The culture is good, and I want to make serious products that serve a purpose. I get paid less than my peers but enough for a living. Is that communistic?

You are simply pricing in external variables to your compensation, which is part of how markets work.

I get what you're saying but I wouldn't program web apps for 3x the pay even. I don't "feel" the American way of switching jobs and being a general purpose programmer.
