So far as I recall, Kevin has got the history down. I will add that State preemption was put on the books in response to Salt Lake City passing some anti-RKBA ordinances. That may have been a bit earlier than the 90s, but may well have been that late as the national anti-gun hysteria heated up.
As Kevin explained, preemption has been strengthened and improved a couple of times since then, most often in response to some tin-hat bureaucrat trying to impose his opinions as law or policy. I would say that 2006 is a fairly reasonable time frame for when public school teachers and other government employees in Utah really got full employment protection if they chose to carry on the job.
So far as I know, under current State of Utah personnel procedures, most State, county, city, school district, public college/university, and other government employees (other than federal of course) in Utah cannot be subjected to anti-gun employment policies. The most obvious exceptions, of course, would be prison guards, mental hospital employees, and court personnel working in areas where guns are specifically prohibited. But school employees in public K-12 schools, plus employees at public colleges and universities, and the gal sitting behind the counter at the DMV (something to consider about being polite), and most other government employees can legally carry a gun on the job with a permit and are protected against any adverse employment action if they choose to do so.
While members of the general public can, with a valid permit, CC or OC in school zones, on school grounds, and even in public schools themselves school districts tend to require employees to keep guns concealed. While this is probably, technically, a violation of State preemption, we've never pushed it because at a practical level, most everyone agrees that CC is more appropriate than OC for teachers and other school employees. We'd also hate to see anything codified with criminal penalties. Also at a practical level, given the anti-gun sentiment of the teachers' union, of too many teachers, and of many administrators, CC has significant personal advantages.
Private schools including Westminster and BYU can have whatever policy they like and both do prohibit guns using general trespassing laws. I know that the private K-12 school we patronize has no issue with the lawful possession of firearms and the last time I offered to arrange a carry permit class for anyone interested, all those with interest (a not insignificant number) already had their permits.
Of course, if we go back before the federal Gun Free School Zone Act of 1990, Utah had no laws against having guns on school grounds. A couple of the older high schools in the SL Valley, for example, have shooting ranges in their basements (long since turned into storage closets no doubt). While my high school in then moderately rural Utah did not have a range, it was not uncommon for students and teachers to have hunting rifles or shotguns in their cars in the parking lot in the 80s. One teacher had decorated his room partially with some of his mounted trophy deer heads. When a school musical production called for the use of a gun shot, I simply borrowed a handgun from a relative, bought some blanks, and brought them in to the teacher who needed them. And most all males from the age of 8 (when the joined cub scouts and got that first pocket knife) right up through teachers and administrators wouldn't think of leaving the house without some kind of pocket or utility knife on their person.
Oh how things have changed, and not always for the better.
