Careful preparation is required for maximising employee engagement with your survey and ensuring it runs smoothly. Essential things to consider before launching your survey include:


  • The number of employees to take the survey.
  • When and for how long the survey should run.
  • Using incentives to boost employee engagement.
  • How you plan to promote the survey.


How many employees do I need to survey?

Ideally, all of your employees should have a say in an employee survey. However, if this is not practical for your organisation, you can survey a sample of the workforce instead. The following recommendations will help you determine how many employees you need to survey and the method required to select your sample of employees. The minimum sample sizes in the table below have been calculated to ensure that your survey findings will be representative of the views of all employees in your organisation.


Total number of workers Administer the survey to:

500 or fewer

All Workers


250 workers


325 workers


350 workers

Over 3000

400 workers


How to select a sample of workers

If you are selecting a sample of employees to survey, it is important that these are selected at random from a list of all your employees. By surveying employees selected through random sampling, you will obtain a best estimate of what represents the views of the whole of your workforce.


Survey timing

It is important to identify what is happening in your employees work lives at the time you want to launch the survey. It is recommended that you:

  • Allow surveys to be completed during work time – this has been shown to improve response rates.
  • Check with others in your organisation who might also be giving a survey. Avoid “doubling” survey chores for your employees.
  • Generally be aware of the time of year you want to give the survey. Where possible, try to pick a time that you know your employees are not loaded with other deadlines that may impact their willingness to participate.


For how long should the survey be open?

We recommend keeping a survey open for approximately three weeks, allowing enough time for employees to access the survey without rushing them, while at the same time not giving them too much time to put off taking the survey.


Pre-survey communications

The main purpose of a pre-survey communication is to prepare the organisation and its internal communications network for the launch, distribution and follow-up of the survey tool. Identify the different communication methods you will use to tell employees that an important survey is coming soon. Try to use as many diverse methods of communication as possible to ensure maximum employee awareness (e.g. posters, debriefings, intranet, e-zines, newsletters, e-mail, pay-slip notes and/or verbal announcements). Identify the critical statements you will make in the pre-survey announcement . Remember that you want employees to be highly motivated to participate. However you choose to word your pre-survey announcement, it is important that you explain to employees the reasons for the survey, including:

  • How and when employees will receive a questionnaire.
  • Why they should participate.
  • Outline the individual confidential nature of the survey.
  • How and when employees will receive feedback on the survey’s results.
  • How actions will be taken in response to the survey’s findings.


Remember to include in your key communication messages:

  • Your organisation is committed to improving employee wellbeing.
  • The participation of all employees is essential to ensure all views are represented.

Sending survey reminders

Sending survey completion reminders is one of the most effective ways to increase response rates. However, it is important to get the tone and frequency right. Carefully planned and managed survey reminders can dramatically improve employee engagement. As with invitations, it is essential to pay attention to the layout and wording of your reminders:

  • Change the reminder’s subject line so that it is not identical to the invitation (or previous reminders).
  • Create a sense of urgency within the subject line and body of the reminder.
  • Remind employees of the purpose of the survey.
  • Remind employees of the value of the survey.
  • Give an estimate of survey completion time.
  • Remind employees that their responses will be anonymous (where applicable).


Sending two or three reminders is considered to be best practice. Although sending survey reminders is one of the most effective ways to boost response rates, it is important not to send too many – if you send reminders too often, contacts may feel harassed and will simply ignore them.
