Compulsory leave is time off imposed by the employer rather than requested by the employee. In the UK, there is no general right for employers to send employees home on unpaid leave. However, specific situations — such as health and safety risks, redundancy, or contractual lay-off provisions — can justify compulsory leave. The legal risks are significant, and getting it wrong can result in claims for unfair dismissal or unlawful deduction from wages.

This guide covers when compulsory leave is justified, the legal framework, and how to handle it safely.

Key takeaways

  • There is no general right for employers to impose compulsory leave — it must be justified.
  • Health and safety risks can justify sending an employee home temporarily.
  • Lay-off clauses in the contract allow unpaid leave when work is unavailable — but only if the contract provides for it.
  • Compulsory holiday is lawful only if the contract allows it and the employee is given reasonable notice.
  • Improper compulsory leave can result in unfair dismissal or unlawful deduction from wages claims.

When compulsory leave is justified

Health and safety

If an employee poses a genuine risk to themselves or others — due to illness, injury, fatigue, or intoxication — you can send them home under your health and safety obligations. The Health and Safety at Work Act 1974 imposes a duty on employers to ensure, so far as is reasonably practicable, the health and safety of employees and others affected by the business.

Sending an employee home for health and safety reasons should be:

  • Based on a genuine, identified risk — not a hunch or preference.
  • Documented with the reason and the evidence.
  • Accompanied by a clear plan for the employee’s return.

Lay-off and short-time working

Where the contract contains a lay-off clause, you can send employees home temporarily when there is insufficient work. This is common in seasonal industries (construction, hospitality, retail). The key requirements are:

  • The contract must expressly provide for lay-off.
  • The employee is entitled to a guarantee payment of up to £35 per day for the first 5 days of lay-off in any 3-week period (2026–27 rate).
  • After 4 consecutive weeks of lay-off (or 6 weeks in any 13-week period), the employee can claim redundancy.

Contractual provisions

Some contracts allow the employer to require annual leave at specific times — for example, a Christmas shutdown. This is lawful provided:

  • The contract expressly allows the employer to dictate when leave is taken.
  • The employee is given reasonable notice (at least twice the period of the leave).
  • The employee is not left without any statutory holiday entitlement.

When compulsory leave is not justified

You cannot impose compulsory leave as a punishment, as an alternative to dismissal, or without contractual authority. The following scenarios are high-risk:

  • Sending an employee home because you dislike them — this is a constructive dismissal risk.
  • Imposing unpaid leave because you cannot afford to pay them — this is an unlawful deduction from wages unless the contract provides for lay-off.
  • Mandatory annual leave during a disciplinary process — this may be seen as a detriment for exercising a statutory right.
  • Compulsory leave without a contractual basis — if the contract does not allow it, the employee can claim breach of contract.

Improper compulsory leave can expose you to:

Risk Basis
Unfair dismissal Dismissal or constructive dismissal for taking or refusing compulsory leave
Unlawful deduction from wages Withholding pay without contractual or statutory authority
Discrimination Compulsory leave related to a protected characteristic (disability, pregnancy, religion)
Breach of contract Imposing terms not contained in the employment contract

Managing compulsory leave safely

To minimise legal risk:

  1. Check the contract — confirm there is a provision for compulsory leave or lay-off.
  2. Document the reason — health and safety risk, business downturn, or contractual shutdown.
  3. Give reasonable notice — at least twice the period of the leave for annual leave.
  4. Pay guarantee payments — if the contract provides for lay-off, pay the statutory guarantee payment.
  5. Review the situation regularly — do not leave an employee on compulsory leave indefinitely.

Frequently asked questions

Can my employer send me home on unpaid leave?

Only if your contract allows it (e.g., a lay-off clause) or there is a genuine health and safety reason. Without contractual authority, compulsory unpaid leave may be a breach of contract.

What is a guarantee payment?

A guarantee payment is up to £35 per day (2026–27) that an employer must pay during the first 5 days of lay-off in any 3-week period, provided the contract allows for lay-off.

Can I claim redundancy after being laid off?

Yes. After 4 consecutive weeks of lay-off (or 6 weeks in any 13-week period), you can claim redundancy and statutory redundancy pay.

Can my employer force me to take annual leave?

Only if your contract expressly allows it and you are given reasonable notice. You must still retain your 4 weeks of statutory leave — the employer can only compel you to take the additional 1.6 weeks of contractual leave.

Is compulsory leave the same as suspension?

No. Compulsory leave is imposed for business reasons (health and safety, lack of work). Suspension is typically imposed during a disciplinary investigation and carries different legal rules.

Putting it into practice

Five steps keep compulsory leave legally safe:

  1. Confirm the contract contains a provision for compulsory leave or lay-off.
  2. Document the reason and the evidence for the decision.
  3. Give reasonable notice and pay any guarantee payments due.
  4. Review the situation regularly and set a clear end date.
  5. Seek legal advice before imposing compulsory leave for the first time.
