That everyone in the office gets a commode chair. This way valuable work time is not wasted in the bathroom. Also, be sure to sign your name at the bottom. If you print your name, they will not take you seriously.
They use a hospital style portable toilet modified to go into a 5 gallon bucket. So picture this with a 5 gallon bucket directly under it. It's at the right height to not have any splash out or chance to 'miss'.
If the buckets are full enough that a splash back is possible then they switch them out for a fresh one.
Once the buckets are full they get a lid put on them and then carried out to sit next to the compost bin, once 3 or 4 are ready to go then they get emptied all at once then washed out.
For all intents and purposes it works just like a regular toilet. You sit down on a seat and do your business. Once you're done you use a cover material such as sawdust to cover and that's it till it's full.
I'm a lot more lax with my own setup. Once my bucket is full I dump it, cover it and switch the bucket out for a fresh one. Takes me 7-10 days to fill one bucket and it's much dryer since I'm a single guy and don't pee in it nearly as often as they do.
