Ask better questions sooner.
By month three, a new hire with access to the knowledge base has absorbed the common overrides, the equipment-specific patterns, the parts shortcuts. The questions they're still asking the senior staff are the genuinely hard ones, the novel faults, the judgment calls. Not the routine stuff.
Senior techs notice this. The new hire isn't coming back with the same question. They're showing up with context, having already checked the manual and the local knowledge, and asking for the piece they couldn't find. That changes the relationship between the new hire and the senior technician. It also builds trust faster.
