The most recent figures show activity in workplaces in Mansfield in the working week to April 1 was 10 per cent lower than during a five-week baseline period recorded before the coronavirus pandemic.
This was up from 11 per cent below normal in the five days to March 25, and one of the highest levels of workplace activity across the UK.
In Ashfield, workplace activity in the two weeks to April 1 was 22 per cent lower than before the pandemic.
In England, domestic legal restrictions ended on February 24 as part of the Government's Living with Covid plan.
Activity in workplaces across the UK was 26 per cent below normal in the most recent week's data – a figure which has remained around the same level since early March.
Separate figures from the Office for National Statistics show that between March 16 and 27, 12 per cent of British adults worked exclusively from home, 57 per cent travelled to work everyday and 14 per cent did a combination of both.
The IFoW, an independent research and development institute, said lockdown restrictions acted as a catalyst for more remote work, with some employers and employees keen to retain the benefits.
A group spokeswoman said it provides the opportunity to work from anywhere, at anytime, and the ability to spend more time with families, but individual home working conditions matter significantly.
She said: “Our research finds individual preferences vary hugely, with some missing the everyday social interactions of a shared work space and experiencing an increased blurring of work-life boundaries.
“Since experience of homeworking varies enormously, it is important for employers to meaningfully consult with their employees on a regular basis about home working in order to minimise risks.”
