Why professional services employees leave and how to understand why
Why associates and managers leave consulting, accounting, legal and advisory firms, and how to ask about progression, workload and partners at exit.
6 min readRead articleAn MEP design consultancy designs the mechanical, electrical and plumbing services that run through a building. Separate discipline teams must produce coordinated drawings on a shared timetable, and one late team holds up the whole issue.

Not sure what you need? Tell us about your business in six short steps and we will come to the first meeting prepared.
Share your requirementsAn MEP consultancy designs air conditioning and ventilation, electrical supply and lighting, plumbing, drainage and fire services for architects, developers and owners. Each discipline has its own engineers and drafters, yet their drawings must fit in the same ceiling, shaft and plant room. Work flows from load calculations and equipment selection to layouts, coordination with the architect and structural team, tender drawings and later site queries. Deadlines come from the building programme, and the architect's changes cascade through all three disciplines. Many firms carry a mix of permanent staff, drafters on short projects and visiting specialists. The wider professional services hub covers what firms of this kind share.
These are the places the people side of this kind of business tends to give way. The rest of this page works through them.
HR here has to work for each of these groups, not only the office. The set-up below is written with all of them in mind.
Each team has its own workload, yet the drawing issue waits for the slowest, and the discipline that finishes early is asked to help without credit.
A duct and a cable tray meeting in the same ceiling void are found at the model review, and the fix lands on whoever has least time.
A new layout means fresh load calculations, new routes and new drawings, and extra hours are rarely recorded or billed.
Short peaks bring in drafters and modellers who leave when the wave passes, taking drawing habits and project knowledge with them.
A young engineer may know one discipline well and nothing of the others, which limits coordination and future leads.
Modelling and calculation tools change, and staff who are not helped to keep up lose confidence or go elsewhere.
When the firm prices and bids at the same time as delivering, the same engineers are stretched across both.
Start with the topics that matter most here: HR Strategy and Workforce Planning; Learning and Development; Compensation, Payroll and Benefits. Then work through the rest. Each topic is written for professional services, not in general.
How many people, in which roles, by when — and what they will cost.
Training planned from need rather than from the calendar.
Salary structure, payroll inputs and a month that closes on time.
Structure, reporting lines and who is allowed to decide what.
Requisition to joining, the same way every time.
A first day that is the same for the fifth joiner as the first.
Records, attendance, leave and the day-to-day HR that must simply work.
Goals, reviews and ratings that hold up in a conversation.
Named backups for the roles that cannot be vacant.
Communication, recognition and the conditions people actually work in.
Two routes — one for complaints, one for conduct — kept separate.
Policies a manager can apply, and obligations with owners and dates.
Induction, records, incident reporting and follow-through.
Who leaves, when, why — and which of them mattered.
Resignation to relieving letter, in a defined order.
Records that survive people, and approvals that do not queue.
A short monthly pack management actually reads.
An HR function that runs the same way every month.

Plan each team's hours against issue dates on one shared view, review it every fortnight and move help early. Waiting until a date is at risk leaves little room to adjust.
A named coordination lead on each project, with time in the plan and the authority to ask other disciplines to change. If coordination is everyone's job, it is usually done late.
Offer a fair pay, a clear end date or a path to a longer role, and recognise their work. Those you cannot keep should still hand over their knowledge.
Depth in one discipline is needed, but some exposure to the others makes better coordinators and future project leads. Small rotations and joint site visits are enough to start.
Name who bids and who delivers, or set fixed weekly hours for tenders. Otherwise your best engineers are pulled across both and neither gets full attention.
First we would ask each discipline head how load is planned today, count clashes found late and see how architect changes are recorded. A shared workload view with a named coordination lead is a natural first piece, and scope goes into writing for your approval.
