If you're not familiar with the Hybrid model, it's a part-time in the office and part-time remote work model where - usually - employers choose how many days have to be spent in office and employees choose which. It's been laid as a compromise between remote and office, but this can easily become the worst of all models because employees end up forced to stay in expensive living areas, commute in miserable conditions, fight to find a meeting room - most likely one of these design-sweat-box-phone-booth-thingy - or worse use an open space area that promotes holding your opinion to yourself - to mostly take online calls you could have had better from home.
The reality that isn't eluding any employees is that this land of compromises is becoming more and more popular for companies because they could not figure out how to make remote work (or likely didn't really look into it) and try to rush out the fix to a dwindling productivity (or sentiment of it). It's also understood that many places are simply using it as a trojan horse to bring people back to the office full time as all get to witness - at times - the weak arguments that are presented to defend the return to office.
There are lots of good reasons to return to the office and making this model work is actually quite simple - beyond transparency:
1/ Don't give the choice to the employees on which days they can take,
2/ Stick to 2 days (or less) per week in office and
3/ Make these days being Tuesday and Thursdays.
Here is why:
This is obviously a hyper simplification, but the key takeaways are:
This way, you actually achieve a higher level of productivity and performance and the compromise line is not "I give you something, so you owe me something". Instead, employers compromise on more remote days than office days while employees compromise on the choice of the days.
Flexibility is achieved, performance is achieved and the strain of the office is made to count as it yields the effects everybody wants.
