Air carrier ramp personnel reported discovering a taxing aircraft with Dangerous Goods cargo was not properly secured with passenger bags. The taxing aircraft returned to gate to correct the loading error and subsequently departed safely.

Narrative

While loading flight to ZZZ1 there were 2 pcs of Dangerous Goods (DG) planned for the flight. It was already close to departure time and we were closed up when the driver came to deliver the DG to the gate. A call was made to the Supervisor whether or not we were to load it. The supervisor said just get a Brake Release then load the commodity. If the commodities are already at the gate; why are we getting a brake release if we are clearly not ready for push? The Lead on the gate is new so listening to her supervisor she did precisely that and in all the hysteria; she forgot to secure the DG with 15 bags. Plane closed up and pushed out with the utmost haste to get that on time departure. Another Ramp Agent on the gate went inside to report this to the supervisor along with myself and the place had to come back to the gate in order to secure the DG properly. There seems to be a lot of issues lately with early brake releases and Dangerous Goods here in Terminal A and I am not confident everyone is getting the proper direction. Briefings are few and far between and when they are held; majority of the employees are outside working and never get to hear these important announcements or briefing items. My two issues are the disregard for SOP when it comes to Brake Release and the pressure Ramp Agents and Leads are under to get on time performance or to avoid getting a delay. Brake releases are happening too often here in ZZZ and the decision is ALWAYS to load the bags or commodities when they arrive anyway. SO the plane still sits at the gate while we load these items so why does it matter if we get the on-time departure for the books. It's still at the gate! It is safer and easier to keep Ground Support Equipment where it belongs on the aircraft and load these items so we can safely do it then close up and get a brake release and push out in a timely manner. Only a matter of time before something happens that the crew can't walk away from.
