I completed the survey.
Make sure your kid picks a random sample and does not use just every survey response he gets. I am hoping he has been taught about this. If not, he should note the population (n=#) of the surveys and the population of the sample size (n=# less the # of population eliminated by random selection). This is one of the most important aspects of any study, as it reduces sample bias. Another thing you could mention to him going forward is the collection of demographic information on such a study (i.e. race/ethnicity, age ranges, salary ranges, location of workplace, gender). This allows for better research as it gives the researcher background on the individual respondents and gives more variables with which to statistically analyze whether different people (in a variable context) either feel the same or different about conflict in the workplace. The great thing about demographic information is that it is not time consuming for respondents, it literally adds the time it takes to read and answer one of the questions on his survey to collect.
Also, his questionnaire is very solid for what he is looking at. A very good example of the Likert scale. I take it his middle selection on the scale represents "neither satisfied nor dissatisfied". He should really denote that in studies using the same data collection method going forward, it is essentially a "even-point" variation of the Likert scale. All in all, you should be proud of the kid.
I am currently finishing my Master's thesis and applying to PhD programs in the criminology field, so this is my bread and butter.
