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 articleA generator rental business supplies power for events, sites and outages, often at a moment's notice. Here is how to run drivers, mechanics and on-site operators who work odd hours and answer urgent calls.

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 requirementsA generator rental business owns diesel generator sets, from small portable units to large containerised machines, and hires them out for weddings, events, construction sites, factories during outages and festival fairs. Its people include dispatch and booking staff, drivers with cranes or trailers, service mechanics, electricians who connect the load, on-site operators who stay with a set for days or weeks, fuel handlers and a small accounts and sales team. Calls arrive at any hour, particularly in storm season, summer peaks and the wedding season. Delivery, connection and breakdown handling happen on the customer's site, often at night, with no supervisor in sight. A machine that fails at an event or hospital reflects directly on the business, and a poorly connected set can injure the person next to it. See also HR for professional services.
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.
GullyHR runs talent acquisition for permanent roles in generator rental. For each role we agree the job description with you, find and screen candidates against it, and support the offer through to joining. Tell us the role and the number of people, and we start there.
We recruit permanent employees. We do not supply contract or temporary staff.
Every business interviews, but few have a written process that works the same way for every role and every interviewer. GullyHR designs yours, from the role brief to the offer, trains your managers to run it, and can run it for you on the roles you hand us.
We agree what the role must deliver, the must-have and nice-to-have skills, and how each will be scored.
Screening call, assessment, interview rounds and decision points, sized to the role and the number of people you hire.
Structured questions for each role family and a rating guide, so two interviewers judge the same answer the same way.
A short briefing for your managers on what to ask, what to avoid and how to give a clear yes or no.
Who approves, how the offer is made, and how candidates are kept informed from first call to joining.
Breakdowns at night or during festivals pull mechanics from home, with no rule on call duty, rest or pay for being available.
A person stays beside a set at a remote site, with long hours, poor facilities and little supervision or contact.
Wrong cabling, earthing or load setting by a rushed electrician puts people at risk, and the knowledge sits in a few heads.
Diesel is stored, issued and topped up with weak records, and fire risk is mixed with disputes over missing fuel.
Weddings, festivals and storms bring many bookings at once, and drivers and mechanics work long hours with no extra hands.
An operator is blamed for a failure caused by overload or maintenance gaps, and has no records to defend themselves.
Long night drives with heavy loads and tight delivery deadlines cause fatigue, and vehicle checks are patchy.
Those who can diagnose engines and alternators are in demand, and the business loses them to bigger fleets and dealers.
Start with the topics that matter most here: Health, Safety and Wellbeing; Employee Administration; Retention and Attrition Management. Then work through the rest. Each topic is written for professional services, not in general.
Induction, records, incident reporting and follow-through.
Records, attendance, leave and the day-to-day HR that must simply work.

Records that survive people, and approvals that do not queue.
A short monthly pack management actually reads.

Build a roster, pay or compensate for availability and give rest after a long callout. Sharing the load stops the same few from carrying it.
Give them a kit list, regular check-in calls, a relief plan and an emergency card. Long solitary jobs need planning.
Use a written checklist with photographs and sign-off by the electrician. Do not rely on memory under time pressure.
Keep a register, count regularly and separate issue from recording. Clear controls protect honest staff from suspicion.
Offer a skill ladder, fair on-call pay and recognition, and involve them in purchase decisions on engines. They leave when treated as interchangeable.
We would ask about night callouts, lone operators and how connections are checked. A sensible first piece of work is an on-call roster with rest and a connection checklist. Scope follows in writing, so you can accept or trim it.
