The Post Has Moved: A Preventative Audit for Role Drift

Most organisations can describe the job they advertised. Fewer can describe the job being done. Between recruitment and the present day, duties are absorbed, cover becomes permanent and informal specialisms quietly attach themselves to particular people. None of this is necessarily poor management. It is often how work gets done when demand shifts faster than documentation. The difficulty arises when the organisation continues to govern, pay and recruit against the original paper.

Role drift is not a clerical issue. It affects job evaluation, pay banding, recruitment shortlists, performance conversations and the fairness of requests made of staff. It also creates hidden dependency: a process that works only because one person continues to absorb an undefined set of tasks. A short audit, run jointly by HR and operations, can surface the gap before it becomes an employment relations or service continuity problem.

Start with the work, not the wording

A role-drift audit should begin with evidence of actual activity, not a rewrite of the job description. Select a representative sample of roles rather than every post. Include a mix of long-serving staff, recent starters, roles affected by restructures and posts where cover arrangements have persisted. The sample should be large enough to reveal patterns and small enough to complete within a few weeks.

Gather evidence from more than one source. Recent task lists, rota records, ticket categories, project allocations, one-to-one notes, handover documents and approval records are all useful. Ask the post-holder and the line manager separately before comparing views. Neither account is automatically correct, but the difference between them is often where the real issue sits. The purpose is not to catch anyone out. It is to establish what the organisation now relies on.

Map documented duties against observed duties

A simple three-column map is sufficient: documented duties, observed duties and variance. For each variance, record frequency, duration, decision rights and consequence. A task performed once during an absence is not the same as a task performed every week for eighteen months. A duty that carries budget authority or regulatory responsibility matters more than an occasional administrative convenience.

Distinguish temporary cover from settled work. If a duty has continued across several review cycles, or is expected to continue, treat it as settled unless there is clear evidence to the contrary. The audit should also note work that has disappeared from the role. A job description that still lists duties no longer performed can mislead recruiters and distort job evaluation just as much as one that omits new duties.

Read the grading and pay signals

Role drift becomes a risk when the substance of a post changes but the grade, pay band or title does not. Look for shifts in decision-making authority, budget responsibility, specialist knowledge, supervision and customer ownership. If these have changed materially, the job evaluation may be out of date. Where pay and grading questions arise, take appropriate advice and apply the organisation's established job evaluation approach rather than improvising a remedy.

Recruitment is another signal. Adverts, person specifications and interview questions based on an old description produce mismatched appointments. Candidates are selected for a post that no longer exists, while the real requirements remain undocumented. The result is predictable: longer ramp-up, performance gaps and early turnover. For HR, the audit should also consider employment relations exposure. Unclear expectations, disputed duties and inconsistent treatment across similar roles are easier to address before a formal grievance or capability process begins.

Test dependency and resilience

Ask a direct operational question: if the post-holder left tomorrow, which duties would be unowned? Which approvals rely on tacit knowledge? Which customer relationships or supplier arrangements sit with one individual because the job description never caught up? Hidden dependency is not only a succession risk. It can distort service levels, delay decisions and make absence cover more expensive than the organisation recognises.

Score roles by criticality and concentration. A post may be low-profile but still hold a single point of failure. The audit should identify where drift has created a reliance on individual goodwill rather than a designed process. That finding belongs in operational risk discussions, not only in HR files.

Decide whether to formalise, revert or redistribute

Not every drift needs a new job description. There are three practical responses. Formalise the change where the work is enduring, necessary and correctly located in the role. Revert where activity is unnecessary, accidental or better handled elsewhere. Redistribute where duties have accumulated in the wrong post and should sit with a team, a different role or a shared service.

Each option carries implications. Formalising may require job evaluation, consultation and updated objectives. Reverting requires clear communication and removal from systems, not just a verbal instruction. Redistribution needs capacity checking, otherwise the audit simply moves the overload. Record the decision, the owner and the review date. Update the job description, person specification, advert and performance measures where appropriate.

Keep the review proportionate

Role drift recurs because organisations change. A light review rhythm is more effective than an occasional heavy exercise. Add a role reality check to quarterly operational reviews or annual job description reviews. Use trigger events such as restructuring, new systems, prolonged absence, parental leave, retirement, contract extensions or regulatory change. Sample rather than census, and report themes to leadership: where drift is concentrated, which grades are affected and which dependencies need action.

The aim is not perfect documentation. It is alignment between the work the organisation needs, the post it pays for and the person it recruits. A role-drift audit gives HR and operations a shared evidence base for that alignment. It also reduces the chance that small informal adjustments become expensive assumptions.
