Onboarding: new employee integration checklist (Day-7 to Day+90)

Quick answer. A structured integration from D-7 to D+90 reduces early-stage turnover by 25–35%. It combines mandatory administrative steps (pre-hiring notice 8 days prior, written contract, personnel register), Day-0 welcome (office tour, buddy assignment, IT setup), progressive integration (role-specific training, pilot projects, weekly manager feedback), and a Day+90 review. Each phase reinforces the new hire's commitment and secures the employer's compliance.

Early-stage turnover—departures within the first 12 months—represents a significant hidden cost for SMEs and startups: equivalent to 3 to 8 months of the position's salary (administrative payroll, training, lost productivity, replacement recruitment). Yet this attrition often stems not from poor hiring decisions but from an inadequate or nonexistent onboarding experience. A startup with its first employee on Day-0 who doesn't know where to sit, how to access email, or what the internal rules are begins with poor morale from the outset.

At Hayot Expertise, we observe a clear correlation: companies that structure onboarding in four phases—pre-hiring, welcome, progressive integration, and review—retain new hires significantly longer and see engagement spike as early as Week 1. This light investment (a few hours of internal coordination) yields outsized returns in sustained retention.

Filing the pre-hiring notice (DPAE)#

The DPAE (pre-hiring declaration) must be filed no earlier than 8 days before the first work day and no later than the last business day preceding the hire. This timeline is strict and non-negotiable:

• Filed too early (> 8 days prior): rejected by authorities; must be resubmitted.
• Filed too late (after first day): URSSAF penalty (10 % surcharge) and potential contract requalification.

Filing channels:

1. Net-Entreprises (free, accessed via SIRET): recommended for SMEs.
2. Certified mail to local CPAM: slower; avoid unless internet access unavailable.
3. URSSAF Portal if you are an Urssaf Connect client.

Required documents: business ID (SIRET or SIREN), employer and employee contact details, employment type (permanent, fixed-term, etc.).

Drafting and signing the employment contract#

A written contract is mandatory for fixed-term and part-time roles, and strongly recommended for full-time permanent roles (Article L1221-6 governs the information given to the employee). Required sections:

Critical: trial period rules (Article L1221-19, French Labour Code) —

These are default legal durations; a collective agreement may shorten (never lengthen without mutual consent). Renewal must be formalized in writing before the first period expires, or the trial period automatically ends and cannot be extended.

Preparing for welcome: equipment, access, and buddy assignment#

One week before arrival, prepare:

1. IT equipment:

   • Computer (basic configuration, antivirus current).
   • Phone (corporate mobile or desk phone access).
   • Email, VPN, cloud storage access (Microsoft 365, Google Workspace, SharePoint as applicable).
   • Temporary or provisional credentials (reset on D0).

2. Physical access:

   • Building access badge or key code.
   • Office or floor key / access.
   • Personal locker or cabinet (if applicable).
   • Parking or transit pass (if offered as benefit).

3. Buddy or mentor assignment:

   • Volunteer from existing staff, ideally with 18+ months tenure.
   • Role: D0 welcome, operational questions, peer introductions.
   • Time commitment: ~1 hour/week for Month 1 (negotiate coverage with manager if workload is high).

4. Manager coordination:

   • Email to incoming manager: sketch of integration plan (training, resources, D+30 expectations).
   • Calendar block for Week 1: flexible hours for onboarding (no critical client work D0–D3).

Update personnel register#

The personnel register (Article L1221-13, French Labour Code) must be kept current: all current employees listed with hire date, position, salary, working hours. Maintained in paper form or digitally (HR software, spreadsheet minimum). Absence = URSSAF penalty (up to €450).

D0: first day – office tour and introductions#

Morning (2–3 hours):

1. Welcome by manager or buddy:

   • Coffee or breakfast (symbolic signal of care).
   • Brief context: sector, revenue, mission (5 min).
   • Role overview and Day+30 expectations (5–10 min).

2. Office tour (20–30 min):

   • Restrooms, kitchen, break room.
   • Assigned workspace, personal storage.
   • Exits, visitor reception area.

3. Department visits (if >10 staff):

   • Brief introduction of each department head.
   • Names of 3–4 people they'll collaborate with most.

Afternoon (1–2 hours):

1. IT account initialization:

   • IT verifies email, VPN, key software access.
   • Test access from employee's workstation.

2. Welcome package review and document handoff:

   • Two signed copies of employment contract (one for employer, one for employee).
   • Company handbook (mandatory signature).
   • Work schedule, vacation calendar, company holidays.
   • Insurance, health plan, pension plan (enrollment documents).
   • Emergency and safety procedures (evacuation, key contacts).
   • Org chart or contact directory.

D+1 to D+3: First operational steps#

• Daily mornings (30 min): manager debriefing on tasks/questions from the day.
• Observer tasks: no critical client responsibility.
• Lunch with team peer (share onboarding experience, build rapport).

Role-specific training and ramp-up#

Sample training matrix by functional area:

Training costs: internal training funded by employer; external training charged to company training budget or employee training account.

Pilot projects and weekly manager feedback#

• D+7 to D+21: assign 2–3 low-stakes projects (supervised closely).
• Weekly Monday meeting (30 min): manager-to-hire feedback loop:
  • Strengths observed, areas for development, clarifications.
  • Brief notes (not formal documentation yet, but mental record).

Culture and compliance integration#

• Company conduct and policy (1 hour): diversity respect, confidentiality, conflict of interest.
• Workplace safety visit (if applicable to sector: construction, chemicals, healthcare): before starting for high-risk roles; by Day+30 for others as routine assessment (do not confuse with post-sick-leave reinstatement visit).
• Team connection (regular lunches, team events): foster social integration.

Check-in at D+30#

Format: manager-to-hire conversation (30–45 minutes, one-on-one).

Agenda:

1. Self-assessment: how is adaptation going? Strengths, challenges?
2. Manager feedback: overall fit, technical mastery, team integration.
3. Peer input (if gathered informally).
4. Adjustments: scope expansion, additional training, remediation if needed.
5. Record-keeping: attendance, absences (illness, vacation).

D+30 to D+90: Progressive scope expansion#

• Increase responsibility: complex dossiers, independent client work, project leadership.
• Ongoing training if needed (based on D+30 feedback).
• Workplace reinstatement visit if applicable (post-medical leave context).
• Prepare trial period close-out conversation (typically Week 10–12 for permanent contracts or 4-month trial periods).

Trial period closure (end of month 2 or 4, depending on role)#

At trial period end, three paths:

1. Confirmation:

   • Sign amendment confirming end of trial and contract continuation.
   • 30-min conversation: role confirmation, Year-1 expectations, career roadmap.

2. Non-renewal or termination:

   • Termination for underperformance: standard dismissal procedures (severance if applicable per collective agreement, notice period, benefits).
   • Non-renewal of fixed-term: simple non-extension (less formal).

3. Trial period extension (if initial trial uncertain but potential recognized):

   • Written agreement before first period expires.
   • Extended duration: capped at legal maximum (e.g., 4 months for operators = 2 × 2-month maximum, no more).

Pre-hire medical exam vs. post-return-from-leave exam (a frequent confusion)#

Information and prevention visit (VIP):

• When: for employees under enhanced individual monitoring (high-risk posts, night work) and specific groups (minors, disabled workers, pregnant women), the visit takes place before or as close as possible to taking up the post.
• For others: the VIP occurs within a maximum of 3 months of hire.
• Cost: employer-borne.

Post-leave reinstatement exam:

• After at least 60 days off (non-occupational illness/injury) or at least 30 days for a work accident or occupational illness (Article R4624-31).
• Does NOT apply to new hires on trial (unless previous leave on record).

Common mistake: conflating the two and scheduling unnecessary medical screening on D0. An informational visit suffices.

Trial period and renewal: strict deadlines#

• Formal renewal: written confirmation before first period ends (mandatory). Past this deadline, trial automatically concludes.
• Maximum cumulative duration: 2 × legal default (e.g., 4 months for operators = two 2-month periods max).

Trial period termination: less formal than standard dismissal#

• No stated reason required (unlike regular dismissal).
• No legal severance (unless collective agreement stipulates more).
• Notice period per collective agreement or contract (typically 0–7 days).

Exception: if dismissal is discriminatory, it is requalified as a standard dismissal with enhanced protections.

Written contract and pre-hire obligations#

Absence of written contract does not void the contract: one exists de facto (by performance). However:

• Employer risks fine (up to €1,500).
• Disputes later = employer burden to prove agreed terms (difficult).

Best practice: written contract + signatures on D0 or D-1, both parties retain copy.

Personnel register requirements#

Missing register = URSSAF fine (up to €450). Format:

• Paper (maintained current) or digital (HR software or spreadsheet).
• Must include: name, hire date, position, salary, working hours.
• Retained 5 years after employee departure.

Recently, a 12-person SME brought us in after losing three new hires within 18 months—all during the first three months. Upon review, we found virtually no onboarding: contracts signed late (sometimes Month+1), IT equipment failed (email inaccessible on D+3), zero training records, and manager feedback absent. The hidden cost? Roughly €60k (payroll + replacement recruitment). The investment on D0? Less than one day of internal coordination and a few hours of training. This case illustrates why structured onboarding is not a "nice-to-have" management practice but a mandatory risk-mitigation process.

We also observe that SMEs underestimate the psychological impact of administrative clarity: a new hire without a signed contract on D0 begins psychologically fragile. And ad-hoc training dilutes effectiveness: one concentrated, structured training day outweighs three weeks of haphazard "learning on the job."

Hayot Expertise recommendation. Document your onboarding journey in four phases for every future hire: pre-admin (D-7), welcome (D0–D3), progressive integration (D+7–D+30), review (D+30–D+90). Assign an owner (manager or HR), create a reusable checklist (even a simple Google Sheet), and gather feedback at D+90: "Was your integration smooth?" This transparency cuts early turnover, cements engagement, and prevents administrative slip-ups (late DPAE, forgotten contracts). For startups, this can be ultra-lean (7–8 actions); for SMEs, more comprehensive (15–20). The ROI is measured in retention and HR peace of mind.
