(2.) When an employee in Division I is required to work in Sunday time to commence or complete a shift forming part of his ordinary week's work, the time so worked shall be paid for as Sunday time only if and to the extent that the total time (including such Sunday time) worked by such employee in the week of which such shift forms a part exceeds such employee's ordinary hours of duty: Provided, however, that in no case shall any greater time be paid for under this paragraph than the Sunday time actually worked.

(3.) Payment will be made to employees in Division I for Sunday time and time worked by them on Christmas Day and Good Friday at the following rates respectively: To employees in receipt of over £270 per annum, 4s. per hour; to employees in receipt of over £200 and not more than £270 per annum, 3s. 9d. per hour; to employees in receipt of over £165 and not more than £200 per annum, 3s. per hour; to employees in receipt of not more than £165 per annum, 2s. 3d. per hour.

(5.) In the case of any employee in Division I who is specially booked on duty on Sunday there shall not be more than one break in the continuity of such employee's time on any Sunday between the times of his being first booked on duty and his being finally booked off duty for the day: Provided, however, that when any such employee is booked off duty on any Sunday to enable him to obtain meals for a period not exceeding one hour for each meal such booking off shall be deemed not to be a break in the continuity of such employee's time on such Sunday.

This regulation shall be deemed to have come into operation on the 27th day of June, 1920.

102. Unless inconsistent with the context or otherwise expressly provided, regulations 103 to 115 inclusive apply only to employees in Division II, and the word "member" in those regulations means and includes any employee in Division II to whom the regulation is applicable in each case.

103. Wherever in regulations 104 to 120 inclusive it is provided that a member shall be paid at his ordinary rate of pay or at a rate which is a multiple thereof, such ordinary rate of pay shall be determined as follows:—

(a.) Where it is provided that a member whose ordinary hours of work are forty-four per week or eighty-eight per fortnight shall be paid at a rate which is a multiple of his ordinary rate of pay, such ordinary rate of pay shall be a rate per hour being one forty-eighth part of the amount which such member would be entitled to receive for forty-four hours' ordinary time at his classified rate of pay.

(b.) In all other cases "ordinary rate of pay" shall mean the member's classified rate of pay in each case.

Provided that in the case of those employees in the Traffic and Locomotive Branches mentioned in regulation 107 who are entitled to payment at one-and-a-quarter times their ordinary rates of pay for ordinary time worked between 10 p.m. and 6 a.m. the ordinary rate of pay shall, for the purpose of calculating payment for overtime or standing-time worked or occurring between the times aforesaid, be a rate per hour being one-and-a-quarter times the ordinary rate of pay as hereinbefore defined in each case.

Every member who reports fit for duty as and when required, and is fit to perform and does duly perform the work allotted to him, shall, subject to the provisions of these regulations, be entitled to be paid a minimum amount for each week which shall be equal to the amount such member would be entitled to be paid for full ordinary time for such member for a week at his classified rate of pay: Provided, however, that a pro rata reduction shall be made in the minimum amount which any member is entitled to be paid for any week under the provisions of this regulation in respect of any time during which such member remains off duty on his own account during such week, and (in the case of any member attached to the staff of any workshop) for any time during which such workshop is closed in pursuance of the practice of the Department heretofore prevailing and during which such member is off duty and for which, in accordance with the practice aforesaid, such member receives no pay. For the purpose of ascertaining the time during which a member may be off duty each day shall be calculated—

(a.) In the case of any member whose regular hours of duty provide for a weekly half-holiday, at four hours for the day on which such half-holiday is usually granted, and eight hours for any other day, and

(b.) In the case of any other member, at one-sixth of such member's ordinary weekly hours of duty.

(2.) For the purposes of this regulation no account shall, except in the case of night-watchmen, be taken of time worked on any Sunday, or of any amount paid in respect thereof.

(2.) Time off duty to which an employee shall become entitled under this regulation shall be granted at a time convenient to the Department, and shall be taken when granted. No employee shall have the right to accumulate overtime so as to obtain extended time off duty, nor shall he or she have the right to have any time off duty which may become due to him or her in respect of overtime worked added to any period of leave of absence to which he or she may be or become entitled.
