Before the formation of 'Unite' Amicus was at the forefront of partnership agreements in the UK. It was the reason that T&G were haemorrhaging members to Amicus. People moving away from the old style T&G were and still are stuck in.
Although the name Unite is there, Unification has not been entirely completed because of the power struggles at the top. If the T&G attitudes prevail then the majority of members will suffer and eventually leave. BASSA being a prime example of the old style of conflict.
When working in partnership strikes were almost non existent because both sides had good reason to negotiate properly. Companies with partnership agreements tended to have the edge for contracts and Terms and Conditions were very good. Harmony is good for everyone.
I know many 'Unite' Amicus members who are watching carefully and looking around for another Union to bring in should the T&G prevail.
