Over 100 rank and file electricians held a national meeting in Manchester last Saturday.
They endorsed a 20‑point series of demands to construction bosses that had been drawn up by electricians in London the previous week.
There was also a meeting in Scotland of 50 people the same day. Both meetings agreed to continue protests against the use of subcontracted labour instead of direct employment.
Electricians in Scotland will focus their campaign on the Southern General hospital site in Glasgow.
The Unite union held a national construction meeting last Wednesday to discuss forthcoming talks with bosses and to elect a committee to be part of negotiations.
The meeting decided that half the committee should be made up of representatives of the rank and file. This was despite opposition from some appointed shop stewards.
Rank and file workers in London held a protest last week at the Shard site near London Bridge. They will return there this week.
