The current five-day strike by British Airways cabin crew has entered its final day. The third wave of walkouts is due to start again from Saturday. With no sign of a breakthrough between BA bosses and the leaders of the UNITE union, the union has also threatened to ballot for more strikes in July. The most recent talks between the two sides ended without agreement yesterday. The dispute centres on pay, staffing levels and working conditions. UNITE is also demanding that BA reinstates the travel perks of striking staff, and ends disciplinary action against others. With another five-day walkout due to start on Saturday, Unite claims it is costing BA 7 million pounds each day.
