SIPTU have announced two 48-hour strikes in February on the following dates:
Thursday 11 February & Friday 12 February
Thursday 18 February & Friday 19 February.
Interestingly the report states that Transdev expect to incur a loss of €700k in 2015 - not quite the rosy picture many people paint about LUAS.
