HR training for managers: 15 topics every new supervisor needs

Last reviewed 27 October 2026 against the sources linked in this post.

In fiscal year 2024 the US Equal Employment Opportunity Commission (EEOC) received 88,531 new discrimination charges, up 9.2% on the year before. Charges like these often turn on how a manager responds. New supervisors are often promoted for doing the job well, not for knowing the rules around it.

This is a list of 15 HR training topics for managers, in 3 sets of 5, so you can pick and mix for a new-manager programme. Set 1 covers the legal essentials, set 2 covers people management and set 3 covers documentation and safety. Every legal topic gets one paragraph that says what the regulator says, with the source in the same sentence. Each set ends with an Our pick, the topic we would teach first, with one line on why.

The legal topics describe US federal rules. Your state, your size and your industry can change them, so use this as a syllabus, not as a ruling.

Set 1: Legal essentials

1. Harassment and retaliation. The EEOC says harassment is unwelcome conduct based on a protected characteristic, and that it becomes unlawful where enduring it becomes a condition of continued employment or where it is severe or pervasive enough to create a hostile work environment. The same page says the harasser can be a supervisor, a co-worker or a non-employee, and that the employer is automatically liable for supervisor harassment that results in a negative employment action such as termination. The EEOC also lists retaliation because the employee complained about discrimination, or helped with an investigation, as prohibited. So a new manager must know two things: how to spot it, and never to punish the person who raised it.
2. Reasonable accommodation for disability. Under the Americans with Disabilities Act, the EEOC's enforcement guidance says an employee can ask for an accommodation in "plain English" and does not need to mention the ADA or use the phrase "reasonable accommodation". That means a manager may be the first person to receive a request, in a hallway or a chat message. The training point is to recognise it and pass it on at once.
3. Pregnancy accommodation. The EEOC explains that the Pregnant Workers Fairness Act requires a covered employer to provide a reasonable accommodation for a qualified employee's known limitations related to pregnancy, childbirth or related medical conditions, unless it would cause an undue hardship. It applies to employers with 15 or more employees, and it prohibits retaliating against an employee for requesting an accommodation.
4. Family and medical leave. The Department of Labor says the Family and Medical Leave Act entitles eligible employees of covered employers to up to 12 workweeks of unpaid, job-protected leave for qualifying family and medical reasons, with group health benefits continued. The employer must be covered, and an eligible employee has worked for it for at least 12 months, has at least 1,250 hours of service in the 12 months before leave starts and works at a location with at least 50 employees within 75 miles. The manager's job is not to decide who qualifies. It is to notice when a leave conversation has started and bring HR in.
5. Wage and hour. The Department of Labor says that, unless exempt, employees covered by the Fair Labor Standards Act must receive overtime pay at not less than one and a half times their regular rate for hours worked over 40 in a workweek. Managers approve time, set schedules and reply to emails at 9 pm, so they need to know that hours worked count. Whether a role is exempt is a question for HR; the DOL overtime page links to the current earnings thresholds.

Our pick: topic 1, harassment and retaliation. It is the topic where a manager's first reaction matters most, and the EEOC figure at the top of this post shows how many complaints reach the agency. Teach the first conversation: listen, do not promise secrecy, do not investigate alone, and escalate the same day.

Set 2: People management

Set 2 is mostly about practice, not law, and only topic 6 touches a legal rule. These topics are what turn a new supervisor from someone who does the work into someone who gets it done through others.

6. Hiring and interviewing. The EEOC says federal law prohibits unfair treatment because of race, colour, religion, sex (including pregnancy, transgender status and sexual orientation), national origin, age (40 or older), disability or genetic information. A new manager who sits on an interview panel should learn to ask every candidate the same job-related questions and to score them against the same criteria. The Legal hiring, interviewing and pay transparency course template covers the detail.
7. Coaching. Show how to ask questions before giving answers, and how to give feedback close to the event. Our guide to coaching in the workplace is a good companion read.
8. Performance reviews. Cover how to set goals, collect evidence all year and avoid rating on the last month only. The employee performance evaluation guide and these performance evaluation examples give new managers wording to start from.
9. Difficult conversations. Practise a three-part opening: what you saw, the effect it had and a question. Role-play is the only way to learn this, so build in time to try it with a colleague.
10. Recognition. Praise should be specific, timely and fair across the team. A new manager who thanks only the loudest person on the team will soon hear about it.

Our pick: topic 9, difficult conversations. Most manager mistakes happen when a talk was put off, and then came out badly. A short, early and calm conversation avoids many of the problems in sets 1 and 3.

Set 3: Documentation and safety

11. Writing things down. Teach managers to keep dated, factual notes: what was said, what was seen, who was there. Opinions and guesses stay out. Good notes are what an HR team reaches for first when a concern becomes a complaint.
12. Investigations. On harassment, the EEOC says an employer can avoid liability for a supervisor's hostile-environment harassment only if it proves that it reasonably tried to prevent and promptly correct the behaviour, and that the employee unreasonably failed to use the employer's procedures. For a new manager the lesson is simple: report the concern to HR promptly and let the trained person lead the investigation. Do not look into it alone.
13. OSHA employer duties. OSHA says employers have a responsibility to provide a workplace free from serious recognised hazards and to provide safety training in a language and vocabulary employees can understand. A supervisor is where that duty meets the shop floor or the office, because they see the spill, the blocked exit or the missing guard first.
14. Incident reporting. OSHA says an employer must report a work-related fatality within 8 hours, and a work-related in-patient hospitalisation, amputation or loss of an eye within 24 hours. OSHA also says many employers with more than 10 employees must keep a record of recordable injuries and illnesses. A manager does not file the report, but they are often the first to know, so they need to know who to call at once.
15. Privacy of employee records. The EEOC says the laws it enforces require employers to keep certain records. That source covers recordkeeping, not confidentiality. Managers handle sensitive information every day: medical notes, leave requests, complaints and pay. Teach a need-to-know rule. Share it only with the people who must act on it, and keep it out of group chats and shared drives. Your own records policy and your state's rules set the detail.

Our pick: topic 12, investigations. Managers often feel they should "get to the bottom of it" themselves. That instinct is understandable and risky. Teaching the hand-off, quickly and with notes, protects the employee who raised the concern and the manager.

How to roll it out

New managers can absorb only so much at once, so spread the 15 topics over the first 90 days.

1. Days 1 to 30: set 1. The legal topics come first, because those are where a mistake can do the most harm. Teach one topic per session.
2. Days 31 to 60: set 3. Documentation and safety fit best once the manager has seen the team at work.
3. Days 61 to 90: set 2. People skills improve with practice, so leave them until the manager has real conversations to learn from.
4. Keep sessions short. Twenty to thirty minutes per topic is enough. End each with one check question.
5. Repeat the check. Ask the same question a month later to see what has stayed.

Ways to host HR training for managers with AhaSlides

You can run any of these topics live, in a classroom or on a video call, and the answers appear on screen as people respond.

1. Pick Answer: one scenario per legal topic. Describe a situation, for example "an employee mentions in passing that they need time off for a medical appointment", and ask the group what the manager should do first. Reveal the answer and discuss why.
2. Word Cloud: "The topic new managers fear most". The biggest word tells you where to start.
3. Rating Scale: "How confident are you?" Ask for a rating from 1 to 5 on each of the 15 topics. Compare the averages before and after training.
4. Open Ended: "Questions for HR". Collect them anonymously, so people ask the question they would otherwise keep to themselves.

If you want a ready-made session, the Harassment prevention for supervisors course template gives you slides to adapt. The ADA and reasonable accommodation, Pregnant Workers Fairness Act, FMLA and wage and hour templates for managers cover topics 2 to 5.

Frequently asked questions

What HR training do managers need?

Harassment, accommodation, leave, wage and hour, and hiring come first. Those are the areas where the EEOC and the Department of Labor set out rules that a manager's everyday decisions can affect. After them, add coaching, feedback and documentation.

Is harassment training required for supervisors?

Not in the federal sources cited in this post, but some states require it. For example, California Government Code section 12950.1 requires employers with five or more employees to give supervisors at least two hours of sexual harassment training, with new supervisors trained within six months of taking the role and everyone retrained every two years. Check your own state's rules.

How long should new manager training take?

Spread it over the first 90 days. Short sessions of 20 to 30 minutes, one topic at a time, tend to work better than one long day.

What is the most important topic for a new supervisor?

Responding to a harassment or retaliation complaint. It is the moment where the manager's first reaction matters most, and the fix is to listen and escalate to HR the same day.

Where to start

Pick one set and use it in your next new-manager session. If you can only teach one topic this month, make it topic 1.
