Do you?
I am junior staff in STEM research, not able to be a budget holder.
I have an old work laptop no one will replace. Some office-mates, and my line managers only use private laptops for Uni research. They bought with personal money, do all admin for. Yes they may not be IT-secure, GDPR etc. compliant but it's cost and employer-should-provide equipment principle rather than security that discourages me doing same. One colleague says it's near universal practice by faculty (to use their own not Uni-supplied computers) in his department. It sounds like they use University computers very little if at all. This way they control updates, install software how they like, security policies, can quickly fix IT issues, get high spec they like, etc.
I'm curious how common this (own not Uni computer as main machine) is in academia outside my institution.
Thanks.
