Hello, Yes the Dept. n by virtue of which, ZP has full powers (with approval from Dir. RD) to transfer any employee to any station.
This happens in all the Dept.s and infact there's a Govt. policy that no employee should remain at same station longer than the specified period of time. (followed or not, is different concern). Like you could've seen the transfers of VOs. many VOs got transferred across the Punjab recently. DDAHs, ADCs, DCs, SDMs, Judges, SSPs, DSPs, SDOs, JEs, everyone gets transferred from one station to another whether away from home or closer.
Your(Any Employee) consent means nothing, because as such the Dept. inherits the right to transfer the employees anywhere as per their discretion provided they had to follow/and they follow rules specified for a particular cadre as mentioned in their service rules. Like in our case, the transfer of a RVO can only be done within the Distt. and secondly, the consent/Approval from Dir. RD is must. And if they're not following the above said criteria, then they can be challenged for fowl play.
