I work in the IT department for my company so I know for a fact that there's no monitoring on the work laptops, which is super strange but whatever.

Still I wouldn't use the work laptop for anything other than work activities because despite the fact I 100% know there's no monitoring I still don't trust it. Besides, It's unprofessional, and although I don't really care about that all that much, it's good to get into the habit of not doing personal activities on a work laptop, because one day they might start monitoring, and this way I'm already in the habit of not doing anything personal.
