Lastly, some companies are adopting a mixture of all these models and letting their employees choose which system they want to adhere to. Basically, when signing a work contract, their workers pick an option and decide if they want to be in the office the majority of the time, or mostly work from home, or be fully remote.
However, there is a potential for imbalances among teams if the majority of workers choose one option, and thereby single out other individuals who chose a different option. This can quickly isolate the one team member in the office or at home and should therefore be planned out in more detail.
