Complaints against officers

[Horse_renoir 5]

Hi guys, seeking advice....i've a little over 12 years service. In the past year i've had three operations on my spine and, while I can still walk, i'm in near constant pain. While it's certainly not ideal,  I'm in the process of trying to get a medical retirement but the pension isn't great. From my reading of the pension rules, I can work so long as it isn't over an average of 33 hours per week. I'm looking at a job with the border force working on the passport control desk at a local airport. The job is advertised as part time. From April until September it's a 36 hour week. The rest of the time it's an 18 hour week, so the average over the year is something like 24 hours. Does anyone know whether the 33 hour average figure is over a rolling year?
