Unions believe the Inland Revenue is about to tighten up on \'self-employed\' people who are really employed.

Before the move from 714 to CIS in 1999, many companies changed staff from 714 to PAYE. Since then there has been a move back towards \'self-employment\'. Now the industry\'s unions believe the Inland Revenue is about to increase its level of activity in the area. The Revenue declines to comment.
