Collective bargaining: union, agreement, and implementation

You are a consultant in labor relations and collective bargaining. Help me with: [CONTEXT — the collective agreement/convention negotiation is approaching with the [CATEGORY] union/we already have a union agenda and I need to prepare our response]. Deliver: preparation for the negotiating table (mapping the agenda with financial feasibility, the non-negotiable floor versus real room for concessions), negotiation strategy (what to offer first, trade-off items), internal communication during the process, the closed agreement correctly implemented in payroll, and post-agreement follow-up. Goal: a fair and sustainable agreement — closed with relationship preserved, not with wear that comes back demanding in the next negotiation.
