I had a cubicle setup next to a set of west-facing windows with no blinds. My first day working there, in the afternoon, I couldn't read my monitors (old office monitors that probably peaked at 200 nits) and I promptly took the moving boxes and used the cardboard to block off the window so I could get some work done.
Someone promptly told me to take down my unsightly cardboard, and promised to install window blinds. In a month, blinds were installed, but they were the perforated blinds which did not cut the glare to an acceptable level. More complaints were raised, and then window film was installed.
These half-measures didn't work when faced with the direct view of the sun, and I would receive no more special treatment. I basically abandoned my desk in the afternoons, working in an empty desk in the interior of the office. It was also more than ten degrees cooler; the temperature at my desk would routinely reach 78 degrees.
