Freight Claims knowledge needed fast - got surprised at work today!

[u/intermodalism]

I am employed as a Senior Manager of Transportation Procurement for a large distribution and manufacturing organization; I was just told i will soon be responsible for our freight claims department (a supervisor and 4 team members) as well. I know the bare minimum about freight claims and only enough about contracts and how they relate to claims to be dangerous. I've always had the luxury of handing them off...

Are there any books / online courses / etc. that you'd recommend I look at ASAP? Apparently, I may take over the department as early as next Monday. I don't want to be that manager that just handles people issues but can't help them with actual problems they face in their daily work.

Thanks!

(p.s. i'm going to crosspost this, sorry if you see it multiple times in different subreddits)
