employees are connected to my neighbor's network with unauthorized network access?
In a nutshell: Yes, absolutely.
At the most fundamental level, using someone else's network without permission is theft of service. Although prosecution is rare, there have been cases where Wi-Fi "squatters" were charged and fined, and ignorance or lax controls are no defense.
Furthermore, unauthorized network access to a neighbor's network bypasses your established security controls and poses a network security threat. When your employees use your neighbor's network, you cannot log their Internet activity. You cannot firewall their traffic to block inbound attacks or outbound back-channels to dangerous sites. You cannot filter email or web payloads for malware or phishing content. You are completely blind to leakage of sensitive data – including regulated information that could lead to a costly breach.
Finally, unauthorized network access from your neighbor to your own network consumes bandwidth and other resources while increasing a network security threat and risk of attack throughout your network. If a harmless neighbor can connect to your network without being detected or blocked, so can a malicious intruder. In regulated industries, failure to control access to sensitive network segments or systems may be considered serious compliance violations. The only exception is a network that is intended to be a wide open public network – and even then you may require terms of service consent to limit your liability for neighbor misuse.
