a friend has been advised to make a grievance and at the same time request info held on their file so that they could see what is held. when friend questioned how this would help they should not sure but sometimes brings up interesting stuff. my friend has never heard of this so my question is is this common when making a grievance and what kind of stuff would that friend find it. the friend just assumes there is typical bog standard hr stuff like personal details and contractual stuff. Also what are the implications of requesting this etc
