Assuming your Clerk has an NALC model contract, one of the following will apply.
Old contract
Subject to clause 2.2 of the contract, the calculation of your annual leave commences from the first day of your employment. You are entitled, in addition to the normal bank and public holidays, to 21 working days’ leave in each leave year (pro rata for part time employees).
In addition to normal bank and public holidays, you will be entitled to two extra statutory days.
Your leave entitlement will increase to 25 working days per year (pro rata for part time employees) when you have five years’ continuous service immediately prior to the commencement of the leave year.
New contract
Full time staff are entitled to 23 days annual leave, plus bank holidays and 2 additional (statutory) days (25 days plus bank holidays). An increase of 3 days is applied following 5 years’ continuous service (28 days plus bank holidays). We will pro-rata that figure where necessary so that your holiday entitlement is in proportion to your working time during the relevant holiday year.
If we need you to work on one of those bank holidays, you will be able to take your holiday on a different day.
So the new contract has clarified the arrangements regarding bank holidays and as the terms do not differ significantly from the old contract, it can be assumed that the same arrangement, although not specified, applied under that contract too.
The working week for local government is currently 37 hours, so a 4-day week would be 29.6 hours, or 128.27 hours per month. On this basis, the entitlement would be four-fifths of the above figures, depending upon which contract you have in place. If your Clerk works 140 hours each month, the entitlement would be slightly greater.
