An employee in a safety sensitive Team Lead role was fairly dismissed for gross misconduct after contaminating a first aid room with lead by repeatedly entering it while wearing contaminated PPE, following a procedurally fair disciplinary process.

The Complainant said he had worked for the Respondent for eight years, had been promoted to Team Lead and had maintained a strong employment record without prior written warnings. He accepted using the first-aid room for breaks, toilet access and personal calls, but denied sleeping there or knowingly contaminating it with lead. He said no sign prohibited access; other employees used the room, and workplace health-and-safety rules were inconsistently enforced. He argued that his supervisor had permitted additional breaks because he regularly worked overtime and covered staff shortages. He also maintained that he had raised several safety concerns, including improper acid disposal, inadequate washing facilities and cross-contamination by other supervisors, yet those matters had not resulted in comparable disciplinary action. He alleged that the investigation had been hostile, procedurally deficient and insensitive to his limited English. He contended that dismissal had been predetermined, disproportionate and imposed without genuine consideration of a lesser sanction.

The Respondent said the Complainant had been a Fire Assay Team Lead with responsibility for staff supervision, quality controls and compliance with procedures governing lead / hazardous chemicals. It maintained that he had received extensive training. Badge records showed that he had accessed the first-aid room for almost thirteen hours between October 2022 and January 2023. The Respondent alleged that he had used the room for non-medical purposes while wearing contaminated PPE, after which lead was detected there. It emphasised that the room had to remain clean and available for injured employees and pregnant workers. The Respondent also relied on his inappropriate email to the colleague who reported him, together with alleged negligence in his Team Lead duties. It said a full investigation and disciplinary process had occurred; representation had been permitted, and dismissal followed because of gross misconduct, lack of remorse, lost trust and serious safety risks.

The Adjudicating Officer found that the dismissal had been fair. The Complainant had occupied a senior, safety-sensitive role. He had received extensive training concerning lead contamination and understood the required hygiene procedures. Further, he had admitted entering the first-aid room in his PPE and using it for additional breaks and toilet access over a substantial period. Badge evidence showed almost thirteen hours of access, while the Respondent’s evidence established that access had been restricted and that lead contamination had been identified. Although the Complainant had raised other workplace safety concerns and had previously been well regarded, those matters did not excuse his own failure to comply with the relevant protocols. He had been informed of the allegations, permitted representation, and afforded an investigation, disciplinary hearing, and appeal. The decision-maker had regarded the contamination risk as sufficiently serious that no lesser sanction was appropriate. The dismissal therefore fell within the range of reasonable responses available to a reasonable employer.

Employers should:

• Ensure that safety rules are clear, documented and reinforced through regular training. Where hazardous substances or contamination risks arise - restricted areas, PPE requirements and other procedures should be expressly communicated by signage, access controls and written acknowledgements. Training records should demonstrate that employees understand the rules and the consequences of non-compliance.

• Conduct a procedurally fair investigation pre-dismissal that clearly identifies every allegation, provides the supporting evidence and permits representation and response. Additional allegations arising during an investigation should be separately notified. The disciplinary decision should explain why the conduct amounted to gross misconduct. Also, why lesser sanctions, including a warning or demotion, were considered inadequate.

• Investigate comparable breaches by managers and colleagues and record any material distinctions between cases. Protected disclosures and unrelated safety complaints should be handled independently so that disciplinary action cannot reasonably appear to be retaliatory.
