Lack of work

I am not at all surprised that the Cadent works on the A52 have now been extended into April because on 3 journeys that I have made past the 'works' on the top of a number 35 bus, I have not seen anybody working. At 2pm on Monday February 20th there were only 3 workmen present. One was leaning against a wall looking at his phone and the other two were sitting on the side of a digger chatting. On Saturday February 25th at around 10am there were no workmen at any point along the whole stretch. On a previous occasion (I cant remember the date) the only work being done was installing some temporary traffic lights. I appreciate that these are just snapshots, but, given the major congestion that is being produced along University Boulevard and the knock on effect this has on traffic trying to leave the A52, I would have expected that Cadent would be being made to work flat out to complete this work as soon as possible, not working at their own lamentable pace.
