I respect your opinions as well. You are absolutely correct that seasonal hires may be jaded at the end of the season. I was jaded last holiday season and I am even more jaded this holiday season.
However, I am sure there is valuable information that can be gained from getting the opinions and insights of seasonal hires. These are people who do not have to worry about angering the permanent STL, ETLs, and TLs and dealing with the consequences throughout the year. These are people who may come from many different backgrounds and fields and choose to work at Target during the holiday season for a variety of different reasons.
If all you ask is the opinions of permanent Target employees, you will always get Target answers.
Target's stock is down nearly 20% this year.
Also, I have read a lot of posts criticizing seasonal hires on here including one thread asking if it is worth even training seasonal hires.
If Target knew what seasonal hires thought, maybe they can change or alter the way they hire and/or train the following year's seasonal hires. Maybe Target can avoid the problems that negatively affect seasonal hires.
Ultimately, Target might be able to attract better quality seasonal hires which would benefit the company/store as a whole, holiday sales, and the quality of those asked to stay permanently.
