Bull****. Research and publication are not optional in any way, shape, or size. You want tenure? You want to even have a prayer of keeping your job? You publish. Or you are out. This is not just true at the massive research one institutions. The only exception would be schools that are strictly teaching only, but more and more of those are trying to force their professors into research because that is where the money is.
At one primarily teaching university with which I am acquainted, the norm is for professors to teach 3 courses per semester with the expectation of at least one grant application, preferably two. That research is assumed to equal one additional course per semester, so the professors get paid for 4 "courses" per semester. At a research one university, I've heard it largely depends on seniority, but sometimes the ratio pivots as low as one class per year with much much higher research output expectations.
