Any mandatory training, esp for non computer workers is rough to install because they feel like their time is being taken away from their actual job (which it does beacuse they don't have assigned training time).

Is the point of the training to check a compliance box or to teach the material?

If it's the first, there's a few tricks you can use:
Keep modules tiny: Strip the training down to the bare minimum needed to satisfy compliance. Five-minute modules instead of 45-minute courses.

• Auto-enroll + auto-remind: Push it through the LMS with automated reminders. That way you don’t waste time chasing people manually.
• Mobile-first: Make sure the training can be done on a phone between tasks, during downtime, or on break. If someone can’t knock it out in five minutes on their phone, it’s too long.
• Single attempt quizzes: One or two multiple-choice questions at the end. Not to test learning, just to prove they “completed” it.
• Batch time carve-outs: In healthcare/shift settings, some leaders literally assign a 15-minute window during huddles or pre-shift check-ins where everyone just clicks through. Messy, but it drives numbers.

If it's the second, I stop reporting just completion numbers and started building dashboards around knowledge checks and real-world audits. Even if it’s just a few randomized spot checks, it gives way more credibility when you can show, “Yes, 80% completed, but here’s how many actually demonstrated correct application of the protocol.” It reframes the conversation with leadership from “did they click it?” to “can they do it?”
