Employment law is one of the most reactive practice areas in UK private practice. Tribunal deadlines are unforgiving, the statutory landscape shifts with every budget, and the phone rings hardest when clients are at their most distressed. Running an employment law firm well demands that you have the administrative scaffolding in place before the next wave of redundancy instructions lands.

This guide covers the operational essentials: managing the Employment Tribunal pipeline, billing for time-sensitive contentious work, building a sustainable retainer base, and using technology to stop routine admin consuming the hours you should be spending on advocacy and advice.

Understanding the Employment Law Caseload Mix

Most employment practices serve two client types that behave almost nothing alike: individual claimants (often legally aided or fixed-fee) and employer respondents (usually billing by the hour or on a subscription retainer). Getting the workflow right for each is critical.

Claimant Work

Claimant-side instructions — unfair dismissal, discrimination, whistleblowing, constructive dismissal — tend to be emotionally charged, administratively dense, and time-limited from the moment of instruction. ACAS Early Conciliation must be initiated before any ET1 is lodged, and the three-month primary limitation period under the Employment Rights Act 1996 leaves very little slack.

According to ACAS’s own statistics, more than 100,000 Early Conciliation notifications are made each year. A significant proportion convert to full ET claims, meaning the average employment solicitor manages a rotating inventory of tight filing deadlines alongside ongoing hearing preparation.

The key operational risk here is diarising. Each matter needs the original act, the EC notification date, the EC certificate issue date, and the resultant extended limitation date tracked accurately. A missed ET1 deadline is usually fatal to the claim and potentially fatal to a PI claim against the firm.

Respondent / Employer Work

Employer clients offer a different administrative profile. A retained HR advisory service or employment law subscription model creates relatively predictable recurring revenue, but requires responsiveness — the value proposition for a £500/month retainer is same-day telephone advice and rapid document turnaround, not billable hours.

Contentious respondent work (ET defences, settlement negotiations, appeals to the EAT) is more margin-rich but project-like. You need a clean handoff between the advice team and the advocacy team, with all correspondence, comparator data, and board instructions on file before the ET3 deadline (generally 28 days from ET1 service).

Employment Tribunal Case Management

From Instruction to ET1

A disciplined intake process prevents the bulk of missed-deadline disasters. For every new claimant instruction, your first step should be a written limitation analysis delivered to the client within 24 hours. This is both good practice and a risk management asset — if the limitation period has already passed, you want that documented before you invest hours in the merits.

The ET1 claim form itself has improved considerably since the online portal upgrade, but preparing the particulars of claim remains time-intensive. A structured precedent bank — separate templates for unfair dismissal, disability discrimination, whistleblowing, and equal pay — dramatically reduces drafting time and ensures you hit every pleading requirement.

Preparation and Disclosure

Once an ET1 is lodged, the case management timeline accelerates. For most straightforward unfair dismissal claims, a Preliminary Hearing is listed within three to four months of lodgement. The ET expects full compliance with its standard case management orders and takes a dim view of last-minute bundles.

Build your matter file structure so that the hearing bundle starts being assembled from day one. Every document the client produces — payslips, emails, disciplinary outcome letters, grievance correspondence — should land in a folder that maps to a standard bundle index. This avoids the brutal weekend sprint before a hearing.

Settlement and ACAS COT3

The vast majority of ET claims settle before hearing. The SRA’s Code of Conduct requires you to give honest advice about prospects, but there is also a commercial reality: a settled case at the right stage is often a better outcome than a hearing win after eighteen months of attrition.

ACAS COT3 agreements and compromise agreements (now called settlement agreements under the Employment Rights Act) have distinct rules. Section 111A of the ERA 1996 protects pre-termination negotiations in unfair dismissal cases. The specific drafting requirements for a valid settlement agreement — independent legal advice, identifying the particular claims compromised — trip up solicitors who stray into employment work without experience. If you offer employment law services, invest in a robust settlement agreement precedent library reviewed by a specialist at least annually.

Billing in Employment Law

Fixed Fees vs Hourly in Contentious Work

The SRA’s transparency rules require employment law firms to publish price information for three specific services where they offer them: employment tribunal claims (employer), employment tribunal claims (employee), and settlement agreements. The indicative price ranges on your website must be accurate, and many firms find this forces a useful internal discipline: what does a standard unfair dismissal claim actually cost to run?

Hourly billing for employment claimants is increasingly rare. The economics rarely work — a £25,000 compensatory award with £15,000 in costs is not a client win. Fixed fees, capped fees, or conditional fee arrangements are more common. For respondent work, hourly rates remain standard but should be supported by a realistic matter budget reviewed at each key stage.

Legal Aid for Employment Work

Legal aid for employment matters is extremely limited. LASPO 2012 removed most employment law from the scope of civil legal aid, leaving only very narrow exceptions: cases with a public law element, cases involving discrimination that also intersect with a social welfare law issue, and cases funded under the exceptional case funding scheme. Relying on legal aid for an employment practice is not a viable business model. If your firm has strong legal aid relationships in housing or family, you may encounter employment issues as a secondary problem — refer them appropriately rather than taking them on as funded work.

Conditional Fee Agreements

CFAs remain widely used for claimant employment work, particularly in discrimination and whistleblowing cases where the compensation potential is higher. The rules on enforceability tightened after LASPO, and any CFA used must comply with the Conditional Fee Agreements Order 2013. A success fee is no longer recoverable from the respondent, which means it comes from the client’s damages — requiring careful client care letter drafting that explains the deduction in plain English.

Building a Sustainable Employment Law Practice

Retainer Products

The most resilient employment practices combine contentious claimant/respondent work with a recurring revenue stream from HR retainer packages. A basic retainer at £350-£600 per month offers SME clients a fixed allocation of advisory time, template contracts and policies, and access to a named solicitor for urgent calls.

Retainer clients also generate the most reliable referral stream. An HR manager who has relied on your firm for three years will naturally refer individual employees who come to them with personal employment problems — or at least, will not actively discourage it.

Building the retainer product requires templating. Your employment contracts (permanent employee, fixed-term, zero-hours), policy suite (disciplinary, grievance, sickness absence, flexible working, anti-harassment), and training presentations should all be pre-built and version-controlled. Customisation time should be measured in minutes, not hours.

Specialist Areas Worth Developing

Employment law is broad enough to carve out lucrative specialisms. Senior executive departures — including directors, LLP members, and high earners with bespoke contractual arrangements — command premium fees and are often time-critical. Settlement negotiations for a departing chief executive with a £300,000 salary, deferred share awards, and a shareholder dispute in the background are a very different product from an unfair dismissal claim.

TUPE transfers (under the Transfer of Undertakings (Protection of Employment) Regulations 2006) arise in outsourcing, business sales, and service provision changes. TUPE advice to the acquiring business in a commercial transaction is often an add-on to a corporate team’s deal work — building that relationship with the corporate department (or with local accountancy firms) creates a reliable referral pipeline.

Technology for Employment Law Practices

Case Management Software

Employment law is better served by adaptable case management software than by tools built specifically for conveyancing or probate. You need custom matter types, flexible deadline tracking, and the ability to attach precedents at the correct stage of a workflow.

The key features to look for are: configurable matter types (separate templates for claimant/respondent/advisory work), deadline calculation tools that account for ET limitation rules, integrated document management with version control, and a billing module that handles both fixed fees and hourly work.

Document Automation

Most employment disputes involve the same twenty or thirty document types recycled across hundreds of matters. A document automation layer that merges client data into pre-approved templates — ET1 particulars, settlement agreements, grievance outcome letters, offer letters — saves measurable hours per matter. ROI on document automation in employment law is typically visible within the first quarter of deployment.

Time Recording

The challenge with time recording in employment law is that a large proportion of work happens on the telephone — quick calls from clients, calls with ACAS conciliators, calls with the Tribunal. Fee earners who rely on end-of-day time recording consistently underrecord by 15-25%. Voice-note based time capture, or mobile apps that allow recording immediately after a call, significantly improve recovery.

Compliance Considerations

SRA Compliance in Employment Law

The SRA’s transparency requirements for employment law pricing are enforceable, and the SRA has fined firms for non-compliant costs information. Your website must display indicative costs, a list of the work included and excluded, the typical timescales, and the seniority of the people who will work on the matter.

AML obligations apply even in employment law — particularly where a retainer client is a business and you are providing ongoing legal advice. Know Your Client obligations require you to verify the identity of business clients and their beneficial owners. This is sometimes overlooked by employment teams who see themselves as primarily advisory rather than transactional.

Disciplinary and Regulatory Risk

Employment disputes occasionally generate professional conduct complaints, particularly in cases where the client had unrealistic expectations about outcome and the fee has been substantial. A robust client care letter, clearly scoped, is your best defence. For contentious matters, ensure that costs updates comply with SRA requirements — a client who feels they were not warned about escalating costs is a client who complains.

Obiter is used by employment law teams to handle the administrative layer that consumes disproportionate fee earner time — reading and triaging incoming client correspondence, drafting acknowledgement letters, logging billable time from calls, and keeping AML records current. Fee earners stay focused on the legal work; the AI handles the admin that would otherwise eat into chargeable hours.
