Dear Hiring Manager,
I am writing to apply for the HR Generalist position at [Company Name]. For the past four years I have been the hands-on HR presence for a 150-employee company, covering the full employee lifecycle: recruiting coordination, onboarding, benefits administration, employee relations, and the compliance work that keeps all of it defensible. I like the generalist's seat precisely because everything crosses it.
The program I am proudest of is our rebuilt onboarding. New hires used to receive a laptop and a wish of good luck; I designed a structured first ninety days with scheduled check-ins, role-specific ramp plans written with each manager, and a feedback survey at day 30 and day 90. First-year retention improved from 76 to 89 percent in the two years since, and our engagement survey now scores onboarding as the company's strongest people process.
The quieter half of the job matters just as much. I administer benefits for all employees and ran our last open enrollment without a single missed election. I maintain our handbook and required trainings, keep files audit-ready, and have supported sensitive employee relations cases - investigations, accommodations, and terminations - with the documentation discipline they demand. Managers come to me early with people problems, which I consider the strongest possible performance review for an HR generalist.
I am drawn to [Company Name] because you are at the size where HR foundations get set, and building those foundations - fair, clear, and human - is exactly the work I want to keep doing.
Thank you for your consideration. I would welcome a conversation about your team's priorities.
Sincerely,
[Your Name]
Run your finished letter through these checks before you send it.
The opening fixes the size of the seat
A 150-employee company tells the reader immediately which generalist job this was: close enough to every employee to know them, small enough that recruiting, benefits, and compliance all land on one desk. That single number saves the reviewer a screening question.
The onboarding number arrives with its mechanics
First-year retention moving from 76 to 89 percent would be an empty claim on its own. It is credible here because the paragraph first describes what changed - a structured ninety days, ramp plans written with each manager, feedback at day 30 and day 90 - and only then reports the result.
It gives the administrative half real weight
Open enrollment run without a single missed election, an audit-ready file room, a maintained handbook. The letter calls this the quieter half of the job rather than skipping it, which is exactly how an HR leader who has cleaned up after a sloppy predecessor reads the role.
Sensitive work is named, not hinted at
Investigations, accommodations, and terminations are listed plainly, with documentation discipline attached and no case details leaked. The line about managers coming early with people problems is the proof underneath it: trust you cannot claim, only evidence.
Change the headcount and the reporting line
Solo generalist for forty people is a different job from one of four generalists supporting nine hundred. Say which you were, who you reported to, and whether you had a coordinator under you, because the rest of the letter is read through that frame.
Swap onboarding for the program you actually own
Leave administration, an HRIS implementation, a rebuilt performance cycle, a compensation banding exercise. Keep the shape the letter uses: the state before, the specific mechanics you built, and the measure that moved afterward.
Reorder the lifecycle list to match the posting
This letter leads with recruiting coordination. If the job description spends three bullets on leave and benefits and one line on hiring, lead with benefits administration instead and let recruiting sit at the end of the sentence.
Name your systems and credentials honestly
Workday, BambooHR, ADP, Greenhouse, PHR, SHRM-CP: include what you have used or hold, in the paragraph where the work happens. If a certification is in progress, give the exam date rather than phrasing that lets a reader assume you already passed.
Reciting the lifecycle as if it were an achievement
Recruiting, onboarding, benefits, employee relations, compliance. Every generalist applicant can list those five words, so the list establishes nothing on its own. Breadth becomes a claim only when one item in it carries an owned program and an outcome.
Being vague about employee relations
"Handled sensitive matters with professionalism" is either filler or an admission that you cannot describe the work. Naming the case types, as this letter does, shows range while keeping every individual case confidential.
Spraying compliance acronyms across a paragraph
FMLA, ADA, FLSA, COBRA, EEO stacked together read as a course syllabus. A reviewer wants one sentence showing you applied a rule under pressure: an accommodation you coordinated, a classification you corrected, an enrollment you closed clean.
Opening with being a people person
It is the most common first line in HR applications and it signals the wrong half of the job. The generalist seat gets hired for judgement and documentation as much as warmth, and the letter should show both in the first paragraph.
Use the ones that are true of you, in the sentences where you describe the work - not as a list bolted to the end. Matching a job description's vocabulary helps a keyword filter find you; it is not what convinces the person who reads the letter afterwards.
Do I need a PHR or SHRM-CP for HR generalist roles?
It depends on the employer and there is no universal rule. Plenty of postings list a certification as preferred rather than required, and experience running real cases often outweighs it. If you hold one, put it in the first paragraph where it is scannable. If you do not, spend that space on a program you owned instead of apologizing for the gap.
How do I write this letter moving up from HR coordinator?
Pick the piece of the lifecycle you already ran without supervision and write the letter around it, then be direct that you are stepping into full generalist scope. Coordinators usually own more than their title suggests: onboarding logistics, benefits questions, file audits. Describe that work at the level you performed it, not at the level of the title.
Should I mention employee relations cases at all?
Yes, at the category level and never at the case level. Say you have supported investigations, accommodations, or terminations, and say what your documentation practice was. Do not describe a specific matter, a department, or anything that could identify a person, even without names. A reviewer reads that restraint as evidence you can be trusted with the next case.
How long should an HR generalist cover letter be?
One page, four or five short paragraphs, roughly 250 to 400 words. This example uses its length on one program with a measured result and one paragraph of compliance detail. If yours runs longer, the paragraph to cut is almost always the one summarizing duties the resume already lists.
