A polarizer can help, but it’s not a guaranteed fix. It works best when the reflection is from a non-metallic surface such as glass, plastic, or lacquer, and when the reflected light is coming from a limited range of angles. In a typical office with many ceiling lights, a polarizer may reduce some glare but usually won’t remove all reflections.

Practical options:

• Try a polarizer and rotate it while viewing the scene to see if the glare drops.
• Change your shooting position; even a small move can reduce specular reflections.
• Shoot from farther away with a longer focal length, which may reduce how many lights reflect toward the camera.
• Diffuse the overhead lights, for example with a white sheet or other diffusion material.
• Override the room reflections with your own lighting setup.
• If possible, turn off some or all office lights, or block specific fixtures causing the hotspots.

In short: yes, a polarizer is worth testing, but controlling angles and the light sources themselves is often more effective.
