Working with temps harms your health and wealth. Not only will you suffer anxiety attacks, you'll get paid less too, according to a new report from the National Institute of Economic and Social Research (NIESR).

英国国家经济和社会研究学院的一项新报告指出，和临时工一起工作有损你的健康和财富。你不但会感到焦虑，收入也会减少。

Temporary workers who come and go as they please drive down the wages of permanent staff by as much as 5pc, the study based on official data claims.

The news is set to inflame¹（激怒） tensions between employees and agency contractors² at a time when millions of permanent staff are enduring pay freezes and cutbacks（削减，裁员） .

Not only do temps spoil wage rates, they make you work harder, too, the report said. Companies that use temps are generally more cut-throat and cost-conscious than those who do not – generating more profit for the bosses but making employees work harder as a result, researchers said.

Staff employed directly by the company have lower job satisfaction and higher anxiety when they can spot agency workers throughout the business – even if those temps are working in different departments, NIESR said.

This is despite permanent staff generally getting paid 9pc more on average than temps.

Alex Bryson, report author, said: "Employers face a dilemma³. Temporary agency workers seem to have an adverse⁴ effect（不利影响） on employees' experiences at work, perhaps due to a more labour-intensive regime, one which is only partly compensated⁵ for with higher wages."

Employees' fears may be short-lived, however, with a separate report this week showing fewer companies are hiring temps since the introduction of new rules giving them more workplace rights.
