Members of the Teachers and Educational Workers Union (TEWU) at the KNUST have started an exercise that may see them staying out of post from Tuesday.The industrial action is in protest of non-payment of some outstanding allowances for the past 30 months.This comes on the heels of the recent strike by the University Teachers Association of Ghana which disrupted academic activities.Chairman of the local TEWU, Charles Arthur says management of the university has been slow in responding to the welfare of the workers.He is therefore demanding that as soon as possible, management resolved issues bordering on overtime allowance, hospital allowance and rectify the “alien promotion” method they have adopted.
