As the public sector pension dispute starts to unravel there is one highly effective tactic that hasn't yet been tried.
Everyone who is facing a change to their pension should take out an individual grievance.
It would cause chaos with employers having to organise millions of hearings - and millions of appeals.
Now is the perfect time as some changes are due to be imposed from April 1.
Changes to individual contracts should only happen after consultation. This has clearly not happened.
DON'T take out collective grievances - that's too easy for managers to deal with.
This is a tried and trusted tactic.
When I was National Union of Journalists' northern organiser we regularly used guerilla grievances to stop or seriosuly modify detrimental contract changes empolyers wanted to impose.
We did it at Sheffield Newspapers, Bradford Newspapers, the Bury Times, Bolton Evening News, Yorkshsire Coast Radio, and the Lancashire Telegraph in Blackburn, to give some examples.

These are smaller groups of workers - imagine the impact if millions of grievances landed on the desk of public sector managers.
Line managers and union reps wouldn't be able to work for weeks - possibly months - as the hearings were held.
This action can be taken by members of unions with leaders that have called off strikes. Even non-union workers can join in.
I hope the March 28 walkout goes ahead with the biggest numbers possible.
Mass grievances - run concurrently - would show the government, and union leaders, that these changes are not acceptable.
