Why don't security guards work at night during the day?

The reasons why day security guards don't work at night are as follows:

1, security guards need to work in shifts, including day shifts and night shifts. The work content and working environment of day shift and night shift are different and suitable for different security guards. Some security companies or places have regulations that require security guards to take turns on duty during the day shift and night shift to ensure the continuity and stability of security work.

2. Some security guards are not suitable for night shift due to personal reasons or health considerations. For example, some security guards have families to take care of, or their physical condition can't adapt to the intensity of night shift work.
