You get right away:
The facts, what works, where your boundary as an employer lies, five building blocks, ten rules for healthier rosters and a worksheet for team agreements on availability.
The cycle you want to break.
Sleep affects work, but work also affects sleep. If all you say is “go to bed earlier”, you miss half the picture.
Step 1.
Work carries on
Emails and worries come home with you.
Step 2.
Not switching off
Your mind stays on, even at ten in the evening.
Step 3.
A restless night
Falling asleep later, waking up earlier.
Step 4.
Less recovery
The next day, work feels heavier. And the cycle starts again.

Larren
Recruitment Lead,
De Selectie
“Recently, I used Deepler to arrive at an EVP. Great what they were able to achieve in a short time! In a period of two weeks, we collected information and were able to continue with our AMC plan. In any other situation, it takes weeks, if not months, to get this done. Contact is good, friendly and constructive. Very nice club to work with.”

Recruiter,
Securitas
“Ideal tool and company to gain more and better insight into the organization and employees as an organization! And especially with speed! For us, it was also the need to get tools for the topics of retention, to prevent future absenteeism or turnover. I also have experience with other parties and I sincerely value the speed of switching, follow-up and personal contact with Deepler. Absolutely recommended.”

Manager,

“What makes Deepler special is that it doesn’t get stuck in numbers. It helps you immediately understand where it is and what teams need. For us, this ensured that employees themselves came up with areas for improvement and took responsibility for them. The insights were sharp and useful, but most importantly: the conversation that started afterwards made the difference. Thanks to Deepler, we didn’t get a paper plan, but change that was supported by the people themselves.”

By better understanding what is going on in the workplace and what people offer as solutions for improvements, we can make more effective decisions. The platform helps us to gain real-time insight and to respond directly to it via the tool.”
