French v Barclays Bank plc [1998] EWCA Civ 1092 is a UK labour law case concerning the contract of employment.

It held that changing a staff manual can breach the term of mutual trust and confidence that is implied into every individual contract of employment, and a unilateral change to a workplace practice can breach that contract.

The staff manual at Barclays Bank plc said he would get a discretionary interest free bridging loan to let him complete the purchase of a new house before selling the old one.

Waller LJ held that the loan scheme was non-contractual and discretionary.

Accordingly unilaterally changing the workplace practice was a breach of the implied term of mutual trust and confidence.
