Abstract
Front-line employees hold valuable insights that can enhance strategic decision-making and operational efficiency, yet their knowledge often fails to reach upper management. This project investigates whether supervisors and middle managers act as barriers to bottom-up knowledge sharing due to hierarchical structures, micromanagement, or lack of psychological safety. We conduct a randomized controlled trial in partnership with a large African bank where supervisors in randomly selected branches receive supportive leadership training. Using employee survey data collected at baseline and endline, we assess the impact of this intervention on knowledge sharing and broader organizational outcomes.

Primary Outcomes

Primary Outcomes (end points)
Employees bottom-up knowledge sharing
Primary Outcomes (explanation)
With our primary outcome variable, we aim to explore how supportive leadership training can influence bottom-up knowledge sharing of critical information. To capture bottom-up sharing, we will run a survey where we ask participants to share critical knowledge on procedures, processes or more that points to current suboptimal situations in the bank.

We will capture both the quantity and quality of bottom-up knowledge sharing.

Secondary Outcomes

Secondary Outcomes (end points)
Mechanisms:
Supervisor-Supervisee Relationship (employee reported)
Leader basic need support (employee reported)
Psychological safety (employee reported)
Perceived Supervisor Knowledge Withholding (employee reported)

Outcomes
Employee well-being,
Employee Retention
Productivity of low performing/junior employees
Secondary Outcomes (explanation)
Apart from our main outcome variable, we will collect several other measures to be able to explore whether and how supportive leadership skills of supervisors influence employees and the organization as a whole.

We will measure leader basic need support using Tafvelin and Stenling (2019).

Experimental Design

Experimental Design
Half of the bank’s branches are enrolled in a supportive leadership program. In these branches, supervisors are invited to attend a two-day leadership training focused on developing effective communication and supportive leadership skills.

Following the intervention, we will compare treatment and control branches to assess whether supervisors act as a barrier to upward knowledge flow. Using revealed behavioral outcomes, we will evaluate the extent to which improved communication and leadership skills help overcome these barriers.
