The credit crunch is causing firms to put pressure on their employees, by calling on them to work while they are sick, which is leading to greater health risks among the, unwell workers and their colleagues and the entire work force.

Figures from the health insurance provider, HSA found that 35 per cent of workers in the Human Resources (HR) profession have been called on to complete basic work tasks and check their e-mails while they are away from work.

Forty-two per cent of British workers have stated that they are less likely to take time off, during the present economic climate and 21 per cent stated that “lingering or background” health issues would not stop them from working.

The HSA also revealed that a worker, who had been losing sight in one of their eyes, did not take time off from work. The cause of the loss of sight was a brain tumor, which eventually caused permanent blindness in their eye.

Richard Halley, head of sales at HSA, said: "Companies are under pressure to get the best out of employees, especially during these tough economic times. However, this should not be done at the expense of employee health and welfare. Companies will only battle through an economic downturn with the support of their employees, and their wellbeing should therefore be of paramount importance."
