What a good time off request includes
Managers approve requests that are easy to say yes to. That means a subject line with the type of leave and the dates, the exact first and last day off, the day you will be back, and a sentence about coverage: who is handling your work, what you will finish beforehand, and whether you will be reachable. A reason is optional for vacation and personal days; for sick leave, bereavement, jury duty and parental leave a short factual line is normal and helps HR code the absence correctly. Keep the whole thing under 150 words.
The generator counts business days, sets your return date to the next weekday after your last day off, and flags requests with less than two weeks of notice. Choose the formal tone for email to a senior manager or HR, and the friendly tone for a manager you talk with every day.
How much notice to give
There is no federal rule on notice for ordinary vacation, so your employee handbook governs. Two weeks is the common minimum for a few days off; a month or more is courteous for a week-long trip, and anything during a busy season should be requested as early as possible. Sick days obviously cannot be planned, but most policies ask you to notify your manager before your shift starts and to send a follow-up note for the file. Jury duty requires you to attend, and most states prohibit firing or penalizing an employee for serving; send the summons as soon as it arrives. For bereavement, tell your manager as soon as you can; many employers offer three to five paid days for immediate family.
Parental leave and serious health conditions may fall under the Family and Medical Leave Act (FMLA). FMLA gives eligible employees up to 12 weeks of unpaid, job-protected leave per year, and requires 30 days' notice when the leave is foreseeable. To be eligible you generally must have worked for the employer for 12 months and at least 1,250 hours, and the employer must have 50 or more employees within 75 miles. Several states (California, New York, New Jersey, Washington, Massachusetts, Oregon, Colorado and others) also run paid family leave programs with their own rules.
PTO rules vary by state
Paid time off is a benefit, not a federal requirement, but once an employer offers it, state law often controls how it is treated. California treats accrued vacation as earned wages: it cannot expire under a use-it-or-lose-it policy and must be paid out when you leave. Colorado, Montana, Nebraska and several other states also require payout of unused vacation at separation, while many states leave it to the written policy. Paid sick leave is mandatory in a growing list of states and cities, typically one hour per 30 or 40 hours worked.
This tool produces a request, not legal advice. If your leave involves a medical condition, a disability accommodation or a dispute over accrued time, check your state labor department's website or talk to HR before you send anything.
