Since GovTech considers itself to be above an average high tech company, maybe it should adopt a more modern HR practice to have a promotion review committee and allow individual to pitch to the committee similar to those upper tier tech companies. Similarity, for job rotation, should allow a person to apply for a higher grade job. Of course, probation can applies. This will also incentivise ppl to rotate instead of stuck in the same place and waiting for their promotion queue number to be called.
