Over 3,000 PCS union members at the 14 offices of the Land Registry (LR) were set to strike on Wednesday and Thursday of this week.
The strike is over threats to jobs and office closures, as well as plans to outsource work.
The immediate threat is LR management plans to introduce a Virtual Post Room.
TNT has been given a contract to open all incoming post, scan documents, funnel the output through software and pass the data into LR computer systems. This threatens over 300 jobs.
Anger increased last week after leaked LR board minutes showed that management was actively planning to move to a joint venture with KPMG.
It denied that any decision had been taken. The Tories have also run a consultation seeking to change LR from a Civil Service trading fund.
It could become a Government Company, a joint venture with a private partner as controlling interest, or be fully privatised.
In all cases oversight would pass to a tiny Office of the Chief Land Registrar, no doubt a typically toothless regulator.
All options are a massive threat to jobs. All of this has fanned the flames. More workers have been joining PCS, and members expect a solid strike across all offices.
