"…on17 February 2004 both claimants in these proceedings were employed under a contract of employment in which there was an implied term of entitlement to payment for 2.5 hours overtime in each working week, and an obligation on the part of the claimants to work said overtime."
"….as at the date of the commencement of the contract, it was not the intention of the respondents to regard the arrangements as contractual …………… we could see there were good reasons for this - the uncertain nature of the requirement in the new situation, the seasonal nature of the job, and how much actual overtime would be required in practice to meet the requirement. If we were looking at this scenario in the spring of 2003, some two or three months after the initiation of the contracts, then we are in no doubt the applications would fail."
"… After more than a year, the arrangements were clearly seen to be working well. The pattern had settled down; no changes had been found to be necessary. Nothing arose which called any part of the arrangements into question, so that these remained in place perhaps as result of inertia as much as anything else."
"Had the circumstances changed so much from the time that the contract was originally struck to suggest that if an officious bystander were to put forward that there ought to be an express provision in the agreement relative to this additional overtime, would both parties have no difficulty in agreeing to that fact."
"Our view therefore is that these arrangements had become contractual. Precisely when this event took place is difficult to say, because of the seasonal nature of the employment. We would have thought that it would be reasonable to regard the overtime as contractual after a period of one complete year, when the maintenance cycle over a 12 month period would be complete. This would take us to February 2004."
"an implied term of entitlement to payment for 2.5 hours overtime in each working week and an obligation on the part of the claimants to work said overtime."
"I do not feel able, in the absence of any other factor pointing to BSC's acceptance of a contractual obligation to pay at least the enhanced basic payment in each case, to infer from the mere fact that it was regularly paid that such a contractual obligation was accepted."
