Not so much a phrase but a memo that is hard to comply with:-
-----------------------------------------------------------------------------
Dear colleague,
All colleagues, including anyone working for and on behalf of BigCo, are reminded that BigCo assets, resource or any site facilities are not to be used for personal use in any form, or for the storage of private property, including vehicles.
Lockers are assigned for the necessary short-term storage of personal items required for BigCo business purposes.
BigCo has no insurance or liability arising for [sic] the storage of any personal property. Any breach is a serious disciplinary matter.
Issued on behalf of [name redacted], Director, Corporate Security and Business Protection and [name redacted], Manager, Corporate Insurance Risk
-----------------------------------------------------
I am trying to reconcile this with the existence of a great big car park, a bike shed, my jacket on the back of my chair and the floor supporting my own briefcase with the odd personal item it that doesn't get used for work.
It reminds me of
