Campaigners protested and blocked roads at the Whitechapel site of the Crossrail project in London on Monday of this week.
For the second time in a week a worker was sacked after raising health and safety concerns.
Last week saw a worker re-employed after protests at the Oxford Circus site.
Campaigners also held a silent vigil at the start of the inquest into the death of Rene Tkacik.
While working on Crossrail Rene was hit on the head by falling concrete from the tunnel’s ceiling in Holborn in March last year.
