Practical solution - that's the way.

Clearly better than "Oh, you should call osha, and neglect completely that 50 other employees apparently don't have any issue".

Search for "Cut Resistant Gloves". Seems to be around 10-20 USD.

This is exactly what butchers do. Dominant hand is bare and wields the meat cleaver. Non-dominant hand holds and turns the meat and wears a chainmail glove.

@LevelRiverSt Welders, mechanics, factory workers, painters, chemists, forestry workers, gardeners....list is endless, it's common for lot of tasks

@user142083 that should read "... that 50 other employees aren't willing to complain". Nobody "has an issue" until after they get injured, and then they can't work, so you wouldn't see them working afterwards.

@JeremyFriesner if it was me I wouldn't complain, I'd just use common sense.... and a glove.... and get on with it

@armand perhaps, but scratches aren't something important, possibly the OP's gf is the only person who got a couple of scratches which is why I suggested a glove.

Wether scratches are important or not is not for us to judge, particularly if they happen on a regular basis over a long period of employment and lead to complications that the employer won't have to answer for in a coutry notoriously backward on health insurance coverage. OP never mentions if other workers face the same problem, but if they open boxes containing broken objects with cutters at a fast pace it is highly unlikely OP's GF's the only one. Temporarily solving the problem on a personal level is better than endure injury, but it's a problem to be adressed at the organization level.

@armand I'm guessing you have a desk job.

Here come the personal deprecating comments. Very classy. I'm guessing you don't give a damn about the safety of people who don't have a desk job.

@armand Most of my life has been blue collar. In the forest a deskjockey forced us all to wear earmuffs once. I didn't hear the team next to us yelling they'd miscut a tree and it came down right on top of me, smashed my helmet, the earmuffs, knocked me to the ground and pinned me beneath what was left of the branches. I wore the helmet through common sense. The earmuffs were the deskjockeys common sense and could have gotten me killed. There's no personal offence intended. If you have no experience at something, then you don't know.

@Kilisi while I honestly respect your experience in your field, the situation is very different and you are actually both arguing the same point: The people actually doing the job should be listened to how the job is best done. Unless you argue people like regularly cutting themselves, management should listen to them, if they have suggestions how they could do their work better/safer.

@Falco just wear the glove, creating drama in this sort of job leads to unemployment.

@Falco They clearly don't have the same point. One person without any experience wants to force you to do something, while the other suggests a more personalized approach.

All work processes can and should be improved.
