"1. In June 1995 I received an updated document (hereinafter referred to as the document) purporting to amend the respondent's sickness provisions.
"It is the unanimous decision of the Tribunal is that it declares:
"Employees incurring absences of 3 or more days per month to a regular pattern should be reviewed as soon as it is fair to say that a pattern has been established. Also, where an employee has had a total of 10 days short-term sickness absence on 3 or more occasions within any period of one year the attendance record should be reviewed as soon as practicable. [Our emphasis] Where formal action is not proposed, informal discussion should take place between the supervisor and the employee, to review the position and check that appropriate assistance is being obtained."
"30. On the critical issue of whether this type of obligation is "apt" to be a term of the contract within the words of Mr Justice Hobhouse in the Alexander decision at paragraph 31, it is our conclusion that it is one of those terms which may be "apt" to be term of the contract depending on all the particular circumstances in question. On the facts before us we have come to the conclusion at the present time that these particular provisions are to be included as part of the contract of employment of the two Applicants before us."
"The principles to be applied can therefore be summarised. The relevant contract is that between the individual employee and his employer; it is the contractual intention of those two parties which must be ascertained. In so far as that intention is to be found in a written document, that document must be construed on ordinary contractual principles. In so far as there is no such document or that document is not complete or conclusive, their contractual intention has to be ascertained by inference from the other available material including collective agreements. The fact that another document is not itself contractual does not prevent it from being incorporated into the contract if that intention is shown as between the employer and the individual employee. Where a document is expressly incorporated by general words of incorporation, whether any particular part of that document is apt to be a term of the contract; if it is inapt, the correct construction of the contract may be that it is not a term of the contract. Where it is not a case of express incorporation, but a matter of inferring the contractual intent, the character of the document and the relevant part of it and whether it is apt to from part of the individual contract is central to the decision whether or not the inference should be drawn.

"Trade Union membership. The policy of the Wandsworth Corporation is wholehearted support for collective negotiation and joint consultation between employer and employee, as it is firmly of the opinion that the establishment and operation of these procedures is mutually advantageous to both parties, and in the public interest."
"Sickness. Officers are required on the first day of absence through sickness or injury to complete and sent the appropriate (G.11) to the Director of Finance and, not later than the fourth day of absence, submit a medical certificate issued by their own doctor to the office or establishment to which they normally report for work.
"Discipline. All officers who have completed a probationary period of service are subject to the Employees' Disciplinary Code, a copy of which will be given to each new entrant at the time of engagement. Copies of this code are displayed at all Corporation establishments and a further copy may be examined or supplied on request. The code also contains details concerning the rights of appeal against disciplinary decisions."
"1. As you may know, the Establishment Committee recently approved new Codes of Practice covering 'Discipline', 'Grievance', 'Sickness' and 'Poor Performance'. Each code contains important changes, the most significant of which is that the power of dismissal now rests with the Director of each Department, with provision for appeal to the Staff Management Committee.

"... this mutual obligation we find as a matter of fact has existed for a number of years and has been viewed by both staff and management as binding on each side."
"In my opinion, the reference to the authorities' rules as amended from time to time shows that it was in the contemplation of the parties that the defenders' rules might be altered. The rules contain no express provision regarding amendment, and the clear inference from the fact that they are the defenders' rules is that the defenders have power to alter them, the only obligation being to enter the amendments in the rules or otherwise record them for the pursuer to refer to within a stipulated period."
