Three started turning off their 2G fallback to the Orange network late last year in areas where they believed that their 3G network was strong enough so that could be the cause of your problem.
In addition Orange and T-Mobile are now working to combine their networks and they are switching off transmitters where they believe they have adequate coverage from one network.
They should be doing this for 2G transmitters at the moment and it could be that the Orange 2G fallback transmitter that Three was using is simply no longer functioning in the area where you work.
I think that Orange and T-Mobile will combine their 3G networks sometime this year and then start switching off 3G transmitters too. Three and T-Mobile have a 3G network sharing agreement but at the moment it doesn't extend to Orange and Three so that could put Three in a worse position once it happens since an Orange 3G mast could replace a T-Mobile one.
There is a possibility that all three networks will combine their assets to produce a single 3G network infrastructure but I haven't seen anything about that yet. Without such an agreement, once the consolidation is over, T-Mobile should emerge with the best network of the three since in addition to it's own network it will have a 2G and 3G sharing agreement with Orange plus a 3G sharing agreement with Three.
