ANCILLARY workers at London School of Hygiene & Tropical Medicine (LSHTM) are to strike over pay and have accused university bosses of blacklisting union activists.

The cleaners, porters, post room and security staff are outsourced workers who are to be taken into direct employment by the university in August after a successful trade union campaign.

They are members of the Independent Workers of Great Britain union (IWGB) and most of the workers are migrants and from black and ethnic minority backgrounds.
