There is no security with the new role and it isnt open to negotiation, why cant people understand that!
Would you be happy if your employer looked round and said "your job is being made redundant but we are going to give you this new one, the terms and conditions are worse, there is no overtime and rest day working and we cannot guarantee how long the job will last, if you dont like it there is the door"!
What would you do, bearing in mind you have got a wife, kids and mortgage to pay!
Yes you are right that isn't good but their must be some points they could negotiate re OBS role such as, it will be classed as safety critical so must adhere to Hidden.
Break length should be same as Conductors
Including booking on and cashing up time within the shift.
Just a side point if a Conductor of 30 years becomes an OBS and 2 years later is made redundant would the redundancy be based on 32 years service or only 2?
