Can you be more specific? I was a union rep for 5 years and might be able to shed some light for you.
What do you mean by dragging their feet? How are you missing out on pay? There's almost always a hefty retro check when it's all said and done.
Are they adjusting starting pay for new hires based on previous experience? i.e Pilot A: first EMS job. On the job 1 year and bumps to step 2. Pilot B comes in at step 3 on day 1 for having EMS experience? That verbage and flexibility is written in most contracts. Is your claim different than this?
