I'm covering a maternity role at the moment as an EA for 3 senior executives and recently one of them has gone on long term sick (no idea when she's back at the moment) so I'm not as busy as I normally am so a bit bored. I've mentioned to my both of the other people I work for and they're fine with it but I'd just like more to do as not used to being this quiet.
My question is would you mention this to HR so just see how things pan out? It's a global company so may well be more work out there but also the paranoid bit of me also worried they might think I've not enough to do and cut my contract short (not been mentioned by anyone btw so very much in my head 
TIA
