Andy is Andy L, not Andy R, which was an error by TT in his first session.
With respect to AL and consulting the union; in large employers, trade union reps are elected by the workforce and some will be paid by the company to be full time union reps and provided with a shared office for union use. This is cost-effective because the HR dept can head off any problems by directly talking to the reps. There will be any number of disciplinary and grievance cases ongoing at any time, and full time reps can use the time to consult with and represent individuals about their cases. It's cheaper than losing paid time on a job for a TU rep to represent and consult.
Some reps in the workplace are not paid but are available for staff to talk to. No paid union rep can be directly hired as a rep. They have to be existing employees elected to the post.
Some policy/conditions issues are easily dealt with as the union will already have policies or custom and practice. Others will mean the union has to consult its members. More serious issues such as pay rises and changes to hours will need to be balloted, and there are strict laws about that.
If an HR department can work with the union to avoid strike action or conflict, then it will. For example HR might say we will give paid time off for staff training. The union will agree and inform members and then negotiate for more. Or they will suggest something more weighty like buying out overtime (salaries increased across the board in exchange for no more overtime claims and an expectation that staff will work additional hours if necessary). That kind of thing is to test the water. The reps may say, nope, not happening, in which case the company will maybe wait another year, or they may say, we can ask the members, and negotiations can start.
(The unions are also good at letting management know about shitty managers who are bullying staff, because often the staff won't speak up to the company but will talk to reps.)
This is in the union's interests because otherwise the company could threaten redundancies. And having paid reps to work with the staff often means compulsory redundancies are avoided and managers don't have to make uncomfortable decisions about who's selected.
For AL this means keeping the union happy as much as possible and negotiating about most things.
My question is what is the union's policy on SSS? Sometimes this is agreed nationally (Unison recently decided that TWAW) and sometimes locally. Do the union members at Leonardo agree with SSS and if they don't, where was the consultation and policy made with their members?
