I don't believe in trying to influence a vote for a union you are not in. But now the vote is over - I would have voted for @zenscara not on her promises (good as they are) but because of what I know she has done. May the wind be at your back.

UCU should lead the way as an employer by employing best practice in its own workplace, and I believe that with @zenscara as GS it would.

The brutal collective punishment in #Gaza must end.

🔴 Indiscriminate attacks must stop now.

🔴 Forcible displacement must stop now.

🔴 Assaults on healthcare must stop now.

🔴 Restrictions on aid and the siege must stop now.

🔴 It all #MustStopNow!

Anyone else getting frustrated by constant empty promises of Internet on new #MerseyRail trains? #MerseyFail
