First time manager training: topics, a sample agenda and the California rules

New managers get sent to leadership training and come back with a vocabulary. What they needed was practice at specific conversations. If I could teach a first-time manager only three things, they would be these:

• Corrective feedback to someone who was a peer last month: the first conversation that tests the new relationship
• Receiving a complaint about a colleague: the conversation that creates an obligation for the employer
• Saying no about money, title or time off: the answer a manager cannot hand to somebody else

Every new manager faces all three within a year, and almost none have practiced any of them out loud before the real one. Leadership theory gives language for the situation without the words for the moment. A manager who can define psychological safety still freezes when an employee starts crying. Practice beats framework: run the conversation, get it wrong in a room where it is safe to, get specific feedback, run it again.

Around those three sit the skills a new manager uses weekly: setting expectations, delegation, one-on-ones, performance conversations, coaching, wage and hour basics and the move from peer to manager. Our article on training managers for the conversation they are avoiding goes deeper on the hardest of them.

This is a sample half-day live session I would run for a new manager group. It is a design, not a finding, and the timings are mine.

Run a short second session at six months, when managers have real situations to bring. It is far more useful than the first and almost nobody runs it. Once at promotion, then again at six months. If you record practice rounds, read recording consent in training first.

First time manager skills checklist

• I can state what good looks like for each person on my team
• I can give corrective feedback without apologizing for it
• I know what I must do the day someone tells me about a colleague’s conduct
• I can say no and explain the reason in two sentences
• I hold one-on-ones on a schedule and keep them for the other person
• I delegate the outcome and not only the task
• I know whom to ask when I do not know the rule

California adds a legal layer for supervisors. Under Government Code section 12950.1, as amended effective September 28, 2020, an employer with five or more employees must provide sexual harassment training to all employees in California. Reading the text through Justia’s reproduction, the core requirements are:

• Two hours of classroom or other effective interactive training for supervisory employees, and one hour for nonsupervisory employees
• Every two years, for each employee in California
• Within six months of assuming a supervisory position, for new supervisors, and within six months of hire for new nonsupervisory employees
• Abusive conduct prevention as a component of the training
• Gender identity, gender expression and sexual orientation content, and practical guidance on the federal and state statutory provisions
• 30 calendar days or 100 hours worked for seasonal, temporary or other employees hired for less than six months

Online courses must contain an interactive feature that requires the viewer to respond to a question periodically, and trainers must have knowledge and expertise in preventing harassment. The regulation at 2 CCR section 11024 points to Government Code section 12926 for who counts as a supervisor, so the title alone does not decide. If the training is a webinar, keep the recording, materials and written questions and responses for two years.

The Civil Rights Department offers a free online training option, according to its December 17, 2025 release. An employer with fewer than five employees falls outside section 12950.1, and training them is still worth doing.

This also answers the demand behind harassment defense training. Under Government Code section 12940, it is unlawful for an employer to fail to take all reasonable steps necessary to prevent discrimination and harassment from occurring, and an employer can be responsible for coworker harassment if it, or its agents or supervisors, knew or should have known and failed to take immediate and appropriate corrective action. Training supervisors is one of the reasonable steps. It is prevention, and it is not a shield.

This article offers general information, not legal advice. Laws change and facts vary, so confirm how they apply to your situation.

The largest legal exposure with new managers is the complaint they handle quietly. The statute above reaches what an employer’s supervisors know or should have known, so a supervisor who decides to keep a complaint to themselves has started an obligation nobody else is aware of. Train that first. It is a 30 minute module and it prevents the most expensive category of mistake.

The practical rule I teach: you do not investigate it, you do not promise confidentiality, and you tell the person you will pass it to HR today and then you do. For the HR side of building a program, see harassment prevention training at Urban Human Resources.

Live practice beats a video for the conversations above, because a conversation is a performance and not a fact. There is some outside support. Ruzuku reports, from its own platform data on 46,545 business enrollments, completion of 59.0 percent for cohort courses against 42.6 percent for self-paced courses. That is one vendor’s data, so treat it as a signal and not a ruling.

For a small business, a virtual first time manager training program works well because the group can be small and the schedule is short. A new manager is an upskilling case, as upskilling vs reskilling explains, and pricing for a group is covered in how to price a workshop. A live half day, a six-month refresh and a self-paced course for the reference material covers most of it. See our live programs and self-paced courses, and the HR team page if you are buying for a group.

Measure the first application. Before the last session, each manager names one task, a date and a reviewer. At 30 days the reviewer says whether the conversation happened and what changed. Add two lagging checks: whether complaints reach HR the same day, and whether the manager’s team members can say what good looks like. I go deeper in how to measure whether training worked.

What should first time manager training cover?

Practice at the three conversations new managers face first: corrective feedback to a former peer, receiving a complaint, and saying no about money, title or time off. Add expectations, delegation, one-on-ones and performance conversations, and in California the harassment prevention layer.

How long should it be?

A live half day at promotion plus a short session at six months works for most groups. The legal minimum is separate: California requires two hours of harassment prevention training for supervisors.

What does California require for supervisor training?

Employers with five or more employees must give supervisors two hours of harassment prevention training, every two years, and within six months of a new supervisor taking the role, under Government Code section 12950.1.

How do I measure whether it worked?

Have each manager name a first application, a date and a reviewer before the last session, then check at 30 days. Track whether complaints reach HR the same day.

Should it be live or self-paced?

Live for the conversations, because practice needs another person. Self-paced works for reference material and for compliance modules with an interactive feature, as the California rule requires for online courses.

Do employers with fewer than five employees need to train supervisors?

Section 12950.1 applies to employers with five or more employees, so smaller employers fall outside it. Training new managers is still worth doing for the same reasons.

What is the first 90 days as a manager supposed to look like?

Listen and set expectations in the first 30 days, build a rhythm of one-on-ones and delegation in days 31 to 60, and hold the first performance conversation in days 61 to 90.
