"The Daily Telegraph previously reported that 1,250 field staff were hired for this Scottish census compared with 7,000 in 2011. It had originally been said that between 3,000 and 4,000 workers would be taken on to carry out home visits."
This.
The 7,000 in 2011 were on 10 hour a week contracts. This time they tried to recruit up to 4000 on 25 hour a week contracts.
I don't know why the posts could not be filled. Too short a contract? 25 hours a week too much to take on for e.g. students with exams coming up, whereas in 2011 10 hours a week was do-able?
Frankly, given the fact that it's been done with only a third of the enumerators required, I'm surprised its not more of a shambles than it is. Covid also meant that quite a few people have been off for a week during the 10 week period - in line with every other business or occupation in the country.
I don't know if it's fair to describe it as a "staff exodus" People had a fixed term contract, had plans for what they would do after the contract ended and aren't accepting the new extension. It's "not staying on" rather than "leaving."
"Sarah Boyack, Labour’s spokeswoman on the constitution, said she had been told staff have struggled with IT problems and that people who were brought in to analyse data have ended up being dispatched to collect information."
Non-enumerators were told that overtime enumerating was available. Not sure that qualifies as being "dispatched to collect information." Enumerators on 25 hour a week contracts have also been allowed to work overtime, if they want.
