Employment Status: Why Substance Matters More Than Contract Clauses
Businesses engaging drivers, contractors or app-based workers.
Explains why simply adding a substitution clause does not guarantee self-employed status.
Incorrect employment status can lead to PAYE, National Insurance, holiday pay and other liabilities.
A recent ruling has provided a timely reminder that substance trumps form in employment status disputes. The mere insertion of a clause into a contract does not automatically change the employment status of workers.
This case concerned an appeal by BCAL, a company providing vehicle collection, inspection, delivery and transportation services. The dispute centred on whether hundreds of drivers were genuinely self-employed or, in reality, workers.
The Substitution Clause – Was It Genuine?
The standard contract allowed drivers to send a substitute. However, the key issue was whether that right was genuine in practice.
Although drivers were theoretically permitted to substitute, the Tribunal examined how the working relationship operated in reality rather than simply relying on the written terms.
Control and Working Arrangements
Evidence showed that:
- Drivers were instructed via an app.
- They generally had no choice over job location, number or type (although they could decline jobs).
- There was evidence of drivers being “punished” for refusing work on available days.
- Fees were set by BCAL with no negotiation.
- Drivers paid weekly administration and insurance contributions.
- DVLA trade plates were issued and controlled by BCAL.
- Drivers were provided with branded equipment, fuel cards, inspection tools and PPE.
- Mandatory in-person training and detailed manuals were required.
Both Tribunals concluded that the substitution clause was not genuine. It was not realistically intended to be exercised in practice.
Substance Over Form
The ruling reinforces a long-standing principle: tribunals look at the reality of the working relationship. If a contractual right, such as substitution, is merely theoretical or an “unrealistic possibility”, it will be disregarded.
Employment status depends on factors such as:
- Control
- Mutuality of obligation
- Integration into the business
- Financial risk and independence
A clause alone does not outweigh day-to-day working practices.
Why This Matters for Businesses
This ruling is particularly significant for companies engaging workers via apps or remote platforms. Simply inserting a substitution clause to imply flexibility or self-employment will not protect against challenge if it is not genuinely exercisable.
Incorrect classification can expose businesses to:
- Backdated PAYE and National Insurance liabilities
- Holiday pay and minimum wage claims
- Penalties and interest
- Reputational risk
Before relying on contractual wording, businesses should review whether their working arrangements genuinely reflect self-employment in practice.
