Trade unions are often perceived as the bane of employers. This perception is understandable when one recalls the occasions when services and production lines have ground to a halt due to strikes and work-to-rule initiatives led by trade unions. It is not every time in instance that employers resort to heavy-handed tactics to thwart the activities of trade unions. Sometimes, more subtle tactics are employed. One such instance is the recent case of Kesatuan Sekerja Industri Elektronik Wilayah Barat Semenanjung Malaysia v Renesas Semiconductor KL Sdn Bhd.
