You cant really swap shifts because of the way the rotation works so if you preferred earlies for example it wouldn't be possible without a 3 way swap and moving rest days, its a nightmare to sort out , only way would be getting accommodated on a shift and tbh that probably wouldn't happen unless its a very good reason and not for a few years anyway.
If thats a problem TL wouldn't be ideal tbh as everyone on the same shift has the same rest days and shifts so you couldn't swap with someone on your shift from a late turn as they'd all be on lates as well, the early drivers are a different shift and have different rest days so its really awkward to do, so like I say unless accommodated its not going to happen.
You basically do 1.5 weeks of lates then 1.5 weeks of earlies back into lates after the long weekend.
You can of course swap with people on your shift for say a later early if you don't want a 4am start for example but that would just be a mutual swap.
The rota is fixed so rest days never change, its a 3 week rotation with long weekend every 3rd week, always finish before long weekend on earlies and always comes back on lates or nights, after the lates the shifts swap back to early after the Wednesday and Thursday rest days.
Car parking is probably easier at three bridges but brighton does have parking.
