The next instalment in our ongoing series of articles offering further insight into what employers should expect from the Employment Bill will concentrate on the changes being introduced in respect of zero hour and low hour contracts.

What type of contracts will be affected?

Many organisations use zero hour and/or low hour contracts to provide flexibility within their staffing arrangements where work levels fluctuate.

Zero hours contracts (also referred to as casual contracts) are a form of contract where a business does not guarantee a minimum number of working hours to an individual worker. Under this form of contract, there is no obligation on the business to provide work and no obligation on an individual to accept work.

Low hour contracts (also referred to as minimum hours contracts) represent a similar arrangement; only in this case a worker is guaranteed a set number of hours but can be offered additional hours as the business requires. As with zero hours contracts, there will normally be no obligation on an employer to offer additional hours and no obligation on the employee to accept them.

What is the current position?

Although often subject to negative press, organisations are currently free to use zero hour and/or low hour contracts as they see fit.

What will change under the Employment Rights Bill?

The Government’s intention is to “make work pay” by providing additional security and predictability for workers engaged under zero hour or low hour contracts. As such the Bill will provide employees with the right to:

The Government have not yet determined what will be treated as “reasonable notice” or on the amount of the proposed cancelation payment that will apply.

Will this change impact agency worker arrangements?

Amendments announced to the Bill in March, mean the changes being applied to zero and low hour contracts will also apply to agency workers. Consequently, the hirer will be responsible for offering regular hours contracts to agency workers and the agency will be liable for cancelation payments. This means it will not be possible for organisations to avoid the impact of these changes by increasing their usage of agency workers.

How should employers prepare for this change?

We currently expect the proposed changes on zero hour and low hour contracts to come into force in 2026.

Organisations that rely on such contracts within their workforce should start reviewing their arrangements to assess the degree of flexibility genuinely required and to consider alternative work arrangements.

At the same time if the current work arrangements regularly see shifts offered on short notice or cancelled without notice then managers should consider how staff planning can be improved to avoid potential compensation payments in the future.
