There's probably no single cause for such a short average tenure length. However, Marcus Lemonis always blames high turnover on bad management. Every time a boss tries to argue with that premise he immediately shuts them down.
Let's try to enumerate possible causes for short tenures:
* Actual job was not the thing promised in the interview
* Hired person and work environment do not "click"
* Got a better paid offer after N months
* Hired person was not up to the task and fired
* Work environment was toxic
* Hired person was toxic
And probably a few more.
In all these cases, IMO there is a much bigger responsibility on the company,because they are the stronger side and the one that has the last word on hiring someone. So, it ends up being manager's fault.
Having been a hiring manager myself, I can only excuse the manager in the case of a really, really, good faker during the interview phase. But those are not the norm.
> and the one that has the last word on hiring someone
False. A lot of times, companies make an offer which are then rejected by a candidate because they have another better offer. Maybe not in 2024, but it was very common until 2022.
If you wanna split hairs - "Hiring" happens only when a contract is signed between a candidate and a company. A candidate can choose not to sign, thus preventing hiring process to complete.
In the spirit of the overall thread, specifically re: your comment "IMO there is a much bigger responsibility on the company,because they are the stronger side and the one that has the last word on hiring someone." - a company is not always on the stronger side. In 2021, a lot of workers had the upper hand.
It still doesn't matter that much when talking about short average tenure. Obviously in a hot market it is going to be more complicated for companies to retain talent, but being a successful company is not an easy task in any case.
Average tenure does not indicate how long someone lasted before leaving the company. If you double the company size in a year you've almost certainly suppressed average tenure to below a year.
