A new supervisor approves a Friday shift swap, then hears "I need time off for treatment" at the coffee machine. From that moment a supervisor's response can bind the employer. In fiscal year 2025 the US Equal Employment Opportunity Commission (EEOC) received 88,201 new discrimination charges, about the same as the 88,531 a year earlier. Leadership training for supervisors that stops at communication skills leaves that gap open.
This is a list of 22 ready-made courses in 4 groups: harassment and fair treatment, employment law, safety and wellbeing, and ethics and culture. Each entry says what it covers, why a supervisor needs it and one interactive moment. Each group ends with an Vores valg.
Legal courses describe US federal rules unless stated. Legal claims link to the regulator.

"Yes" means the topic is covered by a legal duty, described with its source below. It does not always mean the law mandates a training course. California's two hours is the exception.
Harassment, retaliation and fair treatment
Harassment prevention: supervisors (US federal)
The EEOC says the harasser can be the victim's supervisor, and that the employer is automatically liable for supervisor harassment that results in a negative employment action such as termination. The course teaches supervisors to spot and stop conduct early. Interactive moment: a Pick Answer scenario where a team-chat joke crosses the line.
California harassment prevention: supervisors (2 hr)
California Government Code section 12950.1 requires employers with five or more employees to give supervisors two hours of sexual harassment training, within six months of taking the role and every two years. This 120-minute course follows that format. Interactive moment: a Rating Scale check on how confident supervisors feel intervening.
Respectful workplace and anti-bullying
Sets the standard for respectful behaviour and shows supervisors how to act on bullying before it becomes a complaint. Supervisors set the tone daily, so a vague policy fails at the first awkward moment. Interactive moment: a Word Cloud where the team names behaviours that feel disrespectful, then agrees the line.
Preventing retaliation
The EEOC lists repressalier because the employee complained about discrimination, or assisted with an investigation, as prohibited. A supervisor who cools on the person who complained creates exactly that risk. Interactive moment: a Pick Answer quiz on which reactions to a complaint are safe.
Handling conflict in diverse teams
Gives supervisors tools to resolve disputes between people from different backgrounds fairly and early. Supervisors are the first referee, so a one-sided fix becomes a favouritism complaint. Interactive moment: an Open Ended question asking how they would open a conversation between two colleagues in dispute.
Fair assignments and stretch opportunities
Covers how to share tasks and stretch work evenly. Supervisors decide who gets the good assignments, and uneven choices breed favouritism complaints. Interactive moment: a Pick Answer scenario in which one reliable person keeps receiving the best work, and the group chooses the fairer rota.
Our pick: Harassment prevention: supervisors (US federal). It is the course where a supervisor's first reaction matters most, and where a supervisor's harassment ends in a negative employment action, the EEOC says the employer is automatically liable.
Employment law supervisors meet every week
ADA and reasonable accommodation for managers
The EEOC's enforcement guidance says a person can ask for accommodation in "plain English" and need not mention the ADA or use the phrase "reasonable accommodation". Supervisors may hear requests first and should escalate, not refuse. Interactive moment: a Pick Answer quiz of real-sounding requests.
Pregnant Workers Fairness Act for managers
The EEOC says first level supervisors may be particularly likely to receive accommodation requests and should be trained to respond without retaliating. Interactive moment: an Open Ended prompt asking what a supervisor says in the first minute.
FMLA for managers
The Department of Labor says the Lov om familie- og sygeorlov gives eligible employees up to 12 workweeks of unpaid, job-protected leave in a 12-month period for qualifying reasons, and says employers may not interfere with or retaliate over it. Supervisors need to route leave correctly. Interactive moment: a Pick Answer scenario on a sudden absence.
Wage and hour (FLSA) for managers
The Department of Labor says covered employees who are not exempt must receive overtidsbetaling for hours worked over 40 in a workweek, at least time and a half. Supervisors approve the hours. Interactive moment: a Pick Answer quiz on whether a ten-minute handover counts as work.
Performance management and documentation
Teaches fair, specific feedback and dated notes. Documentation is a supervisor's best defence when a rating is later questioned. Interactive moment: a Rating Scale where participants score two sample notes for clarity and fairness, then rewrite the weaker one.
Legal hiring, interviewing and pay transparency
The EEOC says federal law protects applicants against unfair treatment because of race, colour, religion, sex, national origin, age (40 or older), disability or genetic information. Supervisors sit on interview panels and shape offers. Interactive moment: a Pick Answer quiz sorting interview questions into fair and unfair.
Fair performance reviews
Reduces bias in ratings so supervisors can explain every score they give. Review season is where small favourites become big disputes. Interactive moment: a Rating Scale exercise scoring one anonymous employee profile, then comparing the spread of scores in the group.
Supporting working parents and carers
Shows how to handle rotas, flexibility and time off fairly for parents and carers. Supervisors make these calls weekly, and inconsistent answers erode trust. Interactive moment: an Open Ended question on how the team would cover a school-run clash without penalising anyone.
Our pick: FMLA for managers. A supervisor's first reply to "I need time off" is where leave rights are protected or blocked, and it takes one conversation to get right.
Safety leadership and wellbeing
OSHA injury and illness recordkeeping for supervisors
OSHA says an employer must report a work-related death within 8 hours, and an in-patient hospitalisation, amputation or loss of an eye within 24 hours. It adds that many employers must also keep records of injuries and illnesses. Interactive moment: a Pick Answer quiz on which incidents to report.
Supervisor, manager and safety representative duties
Spells out the duties a supervisor carries for safety on their shift and team. OSHA says employers must provide a workplace free from serious recognised hazards, and the supervisor is where that meets the floor. Interactive moment: a Word Cloud of hazards the team sees today.
Safety culture, speaking up and stop-work authority
Teaches supervisors to welcome concerns and use stop-work authority when something looks unsafe. People speak up only when the first report is received well. Interactive moment: a Pick Answer scenario in which a new starter raises a concern five minutes before a deadline.
Safety leadership: visible commitment from supervisors and managers
Shows how visible commitment from the front line shapes whether the team follows safety rules. Teams copy what supervisors do, not what the poster says. Interactive moment: a Rating Scale where participants score how visible their own safety habits are.
Psychosocial risks, mental health at work and workplace violence
Covers early signs of stress, bullying and violence risk. Supervisors see these signs first and need to act early. Interactive moment: an Open Ended prompt asking participants to list the warning signs they have noticed in a team, without names.
Resilience, stress and wellbeing at work
Helps supervisors manage their own stress and stay steady when workload peaks. A supervisor under strain passes it down the line. Interactive moment: a Rating Scale pulse check on energy, workload and support, repeated at the end of the session.
Our pick: Supervisor, manager and safety representative duties. It turns "safety is everyone's job" into the specific tasks a supervisor owns on shift.
Ethics and team culture
Psychological safety for team leads: routines that work
Gives supervisors practical routines for team meetings so people feel safe to raise problems. Problems that surface early are cheaper to fix, and a structured after-action review is one routine that builds that habit. Interactive moment: an Open Ended anonymous question, "What is one thing we should stop doing?", which the supervisor answers live.
Adfærdskodeks
Gives supervisors one clear standard for gifts, honesty, conflicts of interest and speaking up. Supervisors are asked "is this allowed?" more than anyone. Interactive moment: a Pick Answer quiz of grey-area cases, such as a supplier's gift basket.
Our pick: Psychological safety for team leads: routines that work. Every other course here depends on people feeling able to speak, and these routines cost a few minutes a week.
How to roll the plan out
- Law-linked courses and onboarding first. Start with the "Yes" courses in the table. Schedule them within a new supervisor's first weeks.
- Annual refreshers next. Repeat harassment, retaliation and safety, and add any state or country add-on your location needs. California, for example, sets its own two-year cycle.
- Role-specific depth last. Add conflict, reviews and culture courses once the basics are in place.
Keep sessions short, one topic at a time. The case for starting now is the figure from the intro: the EEOC received 88,201 new discrimination charges in fiscal year 2025, about the same as the year before.
Ways to run these courses on AhaSlides
- Selv-tempo: build each course in the AhaSlides course creator so supervisors learn at their own pace.
- Live Q&A deck: run a session after each course so supervisors can ask about real cases.
- Pre and post surveys: measure what changed.
Slide types for this plan:
- Vælg svar: the FMLA quiz asking whether a sudden absence is leave.
- Word Cloud: the hazards the team sees on shift today.
- Bedømmelsesskala: how confident supervisors feel stepping in on harassment, asked before and after.
- Åbent: the anonymous "What should we stop doing?" question from the psychological safety course.
Ofte stillede spørgsmål
What training do supervisors need?
Most supervisors need harassment prevention, basic employment law (leave, accommodation, wage and hour) and safety leadership. The EEOC says first-level supervisors may be particularly likely to receive accommodation requests, which is why the employment law group matters.
Is harassment training mandatory for supervisors?
Some states require it, such as California, where afsnit 12950.1 requires two hours for supervisors at employers with five or more employees. Several other states have their own rules, so check yours. Federal law does not set a specific training requirement, but the EEOC publishes guidance on workplace harassment.
How often should supervisors be retrained?
Every two years in California, and many employers refresh more often than the law requires. California's statute requires supervisor harassment training every two years.
What is the difference between supervisor and employee training?
Supervisor training adds duties to escalate and avoid retaliation. The EEOC says the employer is automatically liable for supervisor harassment that results in a negative employment action.
