Job enlargement is widening a role by adding more tasks at the same level of responsibility. Frederick Herzberg called it horizontal job loading, to distinguish it from enrichment, which adds depth rather than breadth.
Job enlargement vs job enrichment vs job rotation
Job enlargement
Job enrichment

Direction
Horizontal: more tasks
Vertical: more authority
Sideways: different roles over time
What the person gains
Variety and a wider view of the process
Control, ownership, growth
Exposure to other functions
What changes in the role
Scope of tasks
Decision rights and accountability
Nothing; the person moves
Herzberg’s verdict
Adds structural size, not motivation
Creates the conditions for motivation
Treated as a form of horizontal loading
Best used for
Reducing monotony, building process understanding, cover during absence
Enlargement is the cheaper of the two interventions and it solves real problems, provided nobody claims it is a motivation programme.
Reduced monotony. A role split into a single repeated step is fragile and unpleasant. Widening it gives people a fuller task.
Process understanding. Someone who handles three consecutive steps sees the handoff problems that no one owning one step can see.
Operational resilience. Cross-trained people cover absence and demand spikes without temporary hires.
A route into enrichment. Broadening the task base is often the prerequisite for later giving someone the whole unit of work.
Flatter structures. Removing layers pushes task breadth down whether or not it is planned.
What Herzberg actually argued
Herzberg set out the distinction in “One More Time: How Do You Motivate Employees?” (Harvard Business Review, 1968). His two-factor theory separates hygiene factors, such as pay, policy and working conditions, from motivators, such as achievement, recognition for achievement, responsibility and growth.
Horizontal loading, in his account, does not touch the motivators. He listed four things managers do and call enlargement:
Increasing the volume of output expected, such as more units per day.
Adding another routine task to an existing routine task.
Rotating people between jobs that all need enriching.
Removing the hardest parts of a job so the person can do more of the easy parts.
His summary line was that this adds zero to zero. The judgement is harsher than the evidence requires, but the underlying point holds: adding tasks does not by itself create responsibility, and responsibility is what the motivators depend on.
When job enlargement works and when it backfires
Hackman and Oldham’s Job Characteristics Model, set out in “Motivation through the design of work” (Organizational Behavior and Human Performance, 1976), explains the split. Their Motivating Potential Score averages skill variety, task identity and task significance, then multiplies the result by autonomy and by feedback.
Enlargement raises skill variety and sometimes task identity. It does nothing to autonomy or feedback, and those two multiply. So enlargement can lift a score that was already reasonable, and cannot rescue one where autonomy is near zero.
It works when:
The added tasks are adjacent, so the person ends up owning a recognisable whole rather than a longer list.
Training and time come with the change.
Grading and pay are reviewed where scope has genuinely grown.
The person had too narrow a job to begin with.
It backfires when:
It is a headcount reduction with a job-design label attached.
The added tasks are the ones nobody else wanted.
Volume rises with no change in support.
Autonomy stays at zero, in which case more variety just means more of the same constraint.
The retention risk is real. Gallup’s July 2025 research on employee development found employees whose supervisor disapproves of their development efforts are 58% more likely to be looking for a new job. Added work that leads nowhere is read as exactly that.
Job enlargement examples
Role
Before
After enlargement
Payroll clerk
Processes timesheets only
Processes timesheets, expense claims and benefits deductions
Customer service agent
Handles email queue
Handles email, live chat and social channels
Warehouse operative
Picks orders
Picks, packs and books outbound shipments
Recruiter
Screens applications
Screens, schedules interviews and manages the offer paperwork
Marketing executive
Writes email copy
Writes email copy, builds the campaign in the platform and reports on results
In every row, the level of decision-making stays the same. That is what makes it enlargement rather than enrichment.
How to implement job enlargement well
Start from the process, not the person. Map the sequence and find the artificial splits, then widen the role to close them.
Add adjacent tasks only. Unrelated additions create a longer to-do list and no coherent job.
Fund the training. Time and instruction, not a handover document.
Check grading. Where scope has grown materially, review the band. Skipping this is the fastest way to turn enlargement into a grievance.
Cut something. If nothing is removed, this is workload growth, not job design.
Add a vertical element where you can. One decision the person can now make alone converts the change from enlargement to enrichment at almost no cost.
Review at 90 days. Ask what got harder, not whether they like it.
How Engagedly helps
Changing what a role covers only sticks when the new scope is written down and reviewed. Engagedly’s Performance Suite records expanded responsibilities as goals with check-ins and continuous feedback, so a widened role is a documented commitment rather than an informal ask.
The Talent Mobility Suite adds skills profiles, which is what tells you whether an enlargement is building toward a promotion or just absorbing spare capacity.
Job enlargement widens a role by adding more tasks at the same level of responsibility. For example, a payroll clerk who processed only timesheets also takes on expense claims and benefits deductions. The range of work grows, the level of authority does not.
What is the difference between job enlargement and job enrichment?
Job enlargement is horizontal: more tasks at the same level. Job enrichment is vertical: more authority, ownership and complexity. Herzberg argued enlargement makes a job structurally bigger while enrichment creates the conditions for motivation by adding responsibility and growth.
What are the advantages and disadvantages of job enlargement?
Advantages include reduced monotony, better understanding of the end-to-end process, and cross-trained cover for absence. Disadvantages include the risk that it reads as more work for the same pay, workload increases without added support, and no gain in motivation if autonomy stays unchanged.
Is job rotation the same as job enlargement?
No. Job enlargement permanently widens one role. Job rotation moves a person between different roles over time and leaves each role unchanged. Herzberg treated both as horizontal loading because neither adds responsibility to the job itself.
