Concreter on Strike

OK, it's been 4 weeks since the site was cut and we still haven't got the slab. The concreter is not getting his act together. Site Supervisor had to escalate the situation to the construction manager but clearly SS did his best and we can only wait. They finally had the metal bits done end of last week and signed off by the engineer and the certifier. We didn't have a chance to check on it during daytime so don't have a picture to show. SS said that concreter planned to pour the concrete Monday morning (this morning) but he was frank that he didn't really believe the concreter after all this, but I think it will get it done this week anyway. ... I am too optimistic, I know.
EDIT - pictures.
