Can I claim unfair dismissal while still employed?

No — unfair dismissal requires dismissal first. You must have been dismissed to claim it. However, you can bring discrimination, detriment, and wrongful dismissal claims while still employed. If you think you're heading for dismissal, consider whether one of these claims applies to you.

If I raise a grievance, does that pause the tribunal time limit?

No. The 3-month time limit to notify ACAS does not pause while you pursue a grievance. You must start the clock within 3 months of the act of discrimination or detriment, regardless of whether a grievance is ongoing. However, raising a grievance creates evidence and may show the employer had a chance to fix it.

Can my employer discipline me for bringing a tribunal claim?

No — that's victimisation, which is unlawful. If your employer takes action against you because you brought or supported a tribunal claim, that itself is unlawful. Disciplinary action, demotion, exclusion, or any detriment is victimisation. Document it — you have another claim.

What is victimisation and is it unlawful?

Victimisation is detriment suffered because someone (you or a witness) has brought proceedings or given evidence in relation to a protected characteristic. It's unlawful under the Equality Act 2010. Example: you brought a discrimination claim and your employer then denies you a promotion you otherwise would have received. That's victimisation.

Can I claim equal pay while still in the job?

Yes. Equal pay claims don't require dismissal. If you're being paid less than a colleague doing the same or broadly similar work, you can claim while still employed. The claim covers back pay (up to 6 years in some circumstances) and future pay. You don't need to resign or be dismissed.

Should I resign before or after starting a claim?

This depends on your situation. Resigning before means no ongoing employment relationship to manage, but if you're claiming constructive dismissal, timing is critical — don't delay. If you have discrimination or whistleblowing claims, staying employed protects you from constructive dismissal risk. Get advice before deciding.

Can I bring a tribunal claim while still employed?

Many people assume they must wait until dismissal. They don’t. If you’re being discriminated against, harassed, underpaid, or denied adjustments, you can claim now.

Claims you can bring while still employed

These claims don't require dismissal. You can bring them immediately:

Discrimination (ongoing)

Based on age, disability, gender reassignment, marriage, pregnancy, race, religion, sex, or sexual orientation. This can be your day-to-day treatment in the job.

Whistleblowing detriment (ongoing)

If you reported a breach of law and your employer subjected you to detriment (passed over for promotion, excluded from meetings, etc).

Unlawful deduction from wages

Not being paid wages, holiday, commission, or overtime you're entitled to. This accrues while you remain employed.

Failure to make reasonable adjustments (disability)

If you're disabled and your employer refuses reasonable adjustments (flexible hours, equipment, workspace changes), you can claim while employed.

If you're paid less than a colleague doing the same or broadly similar work, claim while employed. Back pay goes back 6 years or more.

Working Time (holiday pay)

If you're not being paid statutory holiday or forced to work excessive hours. Claims accrue while employed.

If you're being harassed by a colleague or manager (related to a protected characteristic), you can claim immediately — before it escalates to dismissal.

Why you might want to claim while still employed

There are strong reasons to claim while you're still in the job:

If you're facing ongoing discrimination or harassment, claiming early may prompt your employer to address it — or at least stops further acts before they worsen.

Avoid constructive dismissal risk

If you're bringing discrimination claims, you don't need to prove constructive dismissal. Claim while employed and avoid that high bar.

Recover ongoing losses

Equal pay and unlawful deductions claims accrue. The longer you wait, the more you can claim (back pay, unearned commission, etc).

Early action creates a record. You've told ACAS, you've filed a claim — this makes it harder for an employer to later claim dismissal was for another reason.

You remain employed and earning while your claim progresses. No gap in income between job loss and tribunal award.

The risks of claiming while employed

Bringing a claim while still employed does carry risks. Be aware:

Employer may become hostile

Your employer may make things unpleasant — but this is victimisation if linked to your claim, and it's unlawful. Document everything and consider it a second claim.

Employment relationship may become untenable

Working for an employer while suing them is difficult. You may find the environment unworkable. Plan a backup exit strategy.

Pretextual discipline

Your employer may discipline you on a made-up basis (poor performance, misconduct). But if it's clearly timed to your claim, it's likely victimisation.

Document every act related to your claim. Keep records of dates, times, emails, who said what. Victimisation claims are powerful — but only if you have evidence.

Interim relief — emergency remedy

If you've been dismissed for whistleblowing or trade union activity, you have an emergency option:

What is interim relief?

An urgent court order keeping your employment continuing pending the tribunal hearing. You keep your job and pay while your case progresses.

Strict time limit: 7 days from dismissal

You must apply within 7 days of dismissal. Miss this and you lose the right. This is urgent — contact ACAS or a solicitor immediately after dismissal for whistleblowing/union activity.

Applies to: whistleblowing and trade union dismissal only

Regular discrimination dismissal doesn't qualify. But whistleblowing is broad — reporting any breach of law, health and safety, environmental law, or miscarriage of justice.

You need legal advice

Interim relief requires sophisticated evidence. You need to show a strong case and that employment relationship can be maintained. Get help immediately.

What happens at the hearing if you're still employed

Tribunals handle ongoing employment normally. But be prepared for changes:

• If you leave before hearing:
• You update your schedule of loss to reflect actual losses (pay you actually lost, not hypothetical future loss). You may still claim injury to feelings and other non-pecuniary losses.
• If you're still employed:
• Your claim proceeds. The tribunal makes the award based on your status at the hearing. If you've received no wages loss (because you're still employed), that's reflected in the award.
• If you leave your job, you have a duty to mitigate — look for alternative work. Money you earn elsewhere reduces your claim. If you leave and sit idle, the tribunal may not award future loss.
