I've been in the workforce for over a dozen years now and something I'm struck by is how little employers are willing to provide reasonable, MINIMAL accommodation to help improve their employees' performance, especially if they're struggling.
The main example of this (that I'm currently enduring…again) is them not honoring shift preferences. People obviously have different physiologies and natural sleep schedules. I'm utterly confounded by how often I see my night owl coworkers barely functioning through early morning shifts and my morning person coworkers practically falling asleep during late shifts. I'm in the latter category (morning person through and through) and will often be given late shifts at various jobs. I always try to get adjust my physiology to late shifts, which never works. So when my performance starts to openly decline and managers vocalize my lapses, I'll politely communicate and let them know it's largely because I'm more of a morning person and feel my work would greatly improve if I had an earlier work schedule.
Almost every time this has happened, management has been rigid and unyielding in accommodating any sort of change, even if there are earlier shifts available. They will then continue to get pissed when my work performance isn't up to par.
What is the reasoning behind this? Why do managers sabotage their staff and themselves this way when they can often easily fix it? Over the years, I've had one entire job where I was working later hours and requested earlier shifts. Management actually honored my request and my work performance improved so drastically I got a promotion. It's wild to me no other companies I've worked for with varying shifts have been accommodating in this way when it would only truly benefit their company.
