Every privilege at work carries a matching responsibility. Grant one without the other and it stops being either.
A coaching principle used in team development; no single originator.
Flexibility, autonomy, trust and perks are privileges. Each one depends on a corresponding responsibility being met, and the pairing has to be said out loud.
The privilege of working from home carries the responsibility of being contactable and delivering. The privilege of setting your own hours carries the responsibility of meeting the deadline. The privilege of spending company money carries the responsibility of accounting for it.
When only the privilege is named, two things happen. It becomes an entitlement rather than an exchange, and withdrawing it later reads as a punishment rather than a consequence.
Say both halves when granting anything. 'You can work from home on Fridays, and what that depends on is X' is a complete sentence. The first half alone is a hostage to fortune.
