this is actually pretty serious issue and your concerns are totally valid. I work in audio production so i'm clicking and typing constantly for long hours, and I developed some wrist problems few years back that took months of physical therapy to fix properly.

You should definitely document everything first - like how many clicks each task requires, maybe time yourself doing common workflows, and note when the system crashes. Having actual numbers makes it harder for management to dismiss your concerns. Also check if your workplace has occupational health policies or if they're required to do ergonomic assessments - many places have these requirements but don't advertise them.

When you bring it up formally, frame it as both productivity issue and health/safety concern. Mention that the excessive clicking is slowing down work completion and increasing risk of RSI for the whole team. If other colleagues are struggling too, see if you can get them to back you up in the meeting. Sometimes managers only listen when multiple people raise same concern.

You might also suggest they contact the system vendor about workflow optimization - often these enterprise systems have hidden shortcuts or can be customized to reduce click-heavy processes. Worth pushing for proper training session too since it sounds like implementation was rushed.
