Driver v Air India Ltd.

Where an employment contract requires work beyond stated basic hours and contemplates payment for overtime, the absence of separately issued notices or circulars does not ordinarily deprive the promise of effect. The employee is contractually entitled to a reasonable payment for overtime that was required, subject to proof that the work was done and was required. Ad hoc overtime may arise without prior authorisation where the employee, particularly a trusted manager responsible for a department, reasonably decides that additional work is necessary. Retrospective verification or certification is ordinarily evidential or supervisory, not a condition precedent, unless the contract clearly provides otherwise. A contractual discretion to approve overtime must be exercised rationally and not arbitrarily.

Mr Minoo Driver worked for Air India under a first contract providing for 37½ basic hours per week, requiring rostered and ad hoc overtime, and referring payment arrangements to notices and circulars. He claimed unpaid overtime, shift allowance, conveyance allowance and telephone expenses. Air India contended that no enforceable entitlement arose because the notices and circulars were absent, and that overtime required prior authorisation or certification.

His claims were dismissed by His Honour Judge Seymour in the Queen’s Bench Division, who also made adverse credibility findings and ordered indemnity costs. Mr Driver appealed. The central questions were whether the first contract created rights to overtime and shift payments, whether approval or certification was a condition precedent, what effect was to be given to the chairman and managing director’s 2005 decision, and how the second contract affected the claims.

1. Appeal allowed. The first contract, read as a whole, gave Mr Driver a contractual right to payment for overtime where overtime was required. Clauses 10 and 11 contemplated remuneration for hours beyond 37½ per week. The missing notices and circulars did not turn that promise into an ineffective agreement to agree. The law could imply a reasonable sum where the contractual payment was not specified. Clause 6 concerned the assignment of duties and could not alter the contractual right to overtime.
2. “Required” did not mean expressly requested or pre-authorised in every case. Ad hoc overtime could arise with little warning. A trusted manager in charge of his own department could reasonably decide that additional hours were necessary, subject to subsequent evaluation of whether the work was done and required. The claim was a contractual right, not a matter of Air India’s unfettered discretion.
3. The first contract imposed no formal condition precedent of advance authorisation, prompt submission or retrospective certification. The documents required monthly submission in arrear for verification. They did not prohibit overtime or make prior approval a condition of entitlement. A wrongful refusal to certify could not destroy the underlying right.
4. The chairman and managing director’s 2005 decision confirmed the existing overtime right and operated retrospectively in addressing long-standing grievances. It also supported entitlement to shift allowance, a fixed £100 monthly conveyance allowance and telephone expenses at £31 per month. Overtime above 48 hours under the second contract was discretionary, but the discretion had to be exercised rationally and not arbitrarily.
5. The trial judge’s findings of fraudulent intent and dishonesty were unsupported by a proper challenge and were materially affected by the erroneous view that no contractual overtime right existed. The claims were to be compensated without diminishing them merely because Air India had failed to scrutinise them. Financial consequences were left for agreement, with disputes to be resolved for the purposes of the order.
6. Longmore LJ agreed, emphasising that ad hoc overtime may arise without prior request or authorisation. Mummery LJ added that “overtime” has no fixed statutory or common-law meaning; its meaning and remuneration depend on the contract and circumstances.
