Aha, the strike is only 'on' Thurs-Fri then Monday for three days so not officially striking at the weekend. That's a pain for them isn't it?!
"UCU has written to the 61 universities* to inform them of an escalating wave of strikes over a four-week period that will begin with a five-day walkout either side of a weekend. There will then be four days of strikes from Monday 5 - Thursday 8 March and a full five-day walkout the following week (12 - 16 March). The strike dates are:
Week one - Thursday 22 and Friday 23 February (two days)
Week two - Monday 26, Tuesday 27 and Wednesday 28 February (three days)
Week three - Monday 5, Tuesday 6, Wednesday 7 and Thursday 8 March (four days)
Week four - Monday 12, Tuesday 13, Wednesday 14, Thursday 15 and Friday 16 March (five days)"
