Night Work and Regulations

What is night time ?
  A period of at least 7 hours. Normally 11pm to 6am but can be varied by agreement

What is the night work limit ? 
  An average of 8 hours for each 24 hour period

Is there flexibility in applying the limit ?
  Yes. A collective or workforce agreement can vary the limits. In addition certain workers are exempt :- 

Those workers whose hours are not determined by an employer e.g. Managing Executives, family workers etc
Those engaged in ‘security and surveillance activities where round the clock activity is required’ e.g. hospitals, residential    institutions, prisons, airports, radio and TV, or where there is a foreseeable surge of activity’ e.g. agriculture, tourism, postal    services.

Unlike the National Minimum Wage legislation the working time regulations do apply to trainees who are engaged on work experience or training such as New Deal or those on National Traineeships.   However, the directive allows individuals to ‘opt out’ of the 48 hour limit. For this to occur there must be a written agreement between the employer and the employee with an option to withdraw from the agreement with written notice of at least 7 days and not exceeding 3 months.


Adolescent Workers

An adolescent worker is someone who is over the Minimum School Leaving Age but under 18. In addition to the other regulations adolescent workers are entitled to:-                 

       a right to free health and capacities assessments for night work
       a right to 12 hours rest a night
       a right to two days off each week
       a right to at least a 30 minute break period if the working day is longer than 4 1/2 hours

How are average hours calculated?
 The average is calculated by monitoring hours over an agreed period. The recommended period is 17 weeks.

What will happen if the worker has 2 jobs?
 The employer should take all reasonable steps to ensure a worker does not exceed an average of 48 hours per week in total and, if  exceeded, confirm they are willing to do so.

How will the regulations be enforced?
 By the Health and Safety Executive for factories, building sites, mines, farms, fairgrounds, quarries, chemical plants, nuclear  installations, schools and hospitals.

By the local authority Environment Health Department for retailing, offices, hotels, catering, sports, leisure and
consumer services

Employment tribunals will enforce workers’ entitlements to days off, rest breaks and paid annual leave.

What records do employers have to keep?
‘Adequate’ records must be kept of the weekly working time of employees. If hourly paid, wage records may be sufficient. If standard working hours are stipulated, ‘management systems’ must be adequate to ensure compliance.

‘Adequate’ records to show the limits on night work are not exceeded must be kept. Records of health assessments must also be kept.

The Government has now removed the need for employers to keep records of the hours worked by individuals who have opted out of the 48 hour week.

What is a health and capacities assessment for a night worker?
There is no prescribed procedure. The Regulations suggest the use of a questionnaire to identify health problems
that may preclude night work according to the opinion of a health professional. 

A health and capacities assessment for an adolescent who works between 10.00 p.m. and 6.00 a.m.will also have to take into account the relative lack of physique, maturity and experience of a young person compared with an adult. 

What about bank and public holidays?
There is no statutory entitlement to them. Where a worker is paid for a public holiday this will count towards their entitlement to annual leave. 

What about part time workers and leave?
Part time workers receive a pro-rata proportion of the full-time annual leave.

Are there any workers exempt from the Regulations?
 Those in :--         

Air, rail, road, sea and canal transport.
Offshore work
Sea fishing
Doctors in training
