West Anglia side of Greater Anglia has:
No booking on before 05:00
No booking off after 01:00
(The GN side of GTR miss this condition the most, as it went when harmonisation took place between GN and Thameslink under First Capital Connect)
Maximum 10 hour day.
Commitment to work ALL Sundays rostered (although you can get someone else to cover a shift if they want to and are available)
I *think* it's flat rate on Sundays.
I might not have up to date information, so happy to be corrected on all of that.
GTR have:
Turns can book on or off at anytime. New drivers are not part of the taxi agreement.
Commitment to work 12 rostered Sundays per year (three per quarter). You can get someone else to work one of these for you if they want to and are available.
Maximum turn length 9 hours 54 minutes.
Sundays pay time plus 55%.
West Anglia - each depot has one big link everyone is in. This makes it easy to swap shifts or weeks of work, as route and traction knowledge isn't an issue. Same with swapping holiday weeks.
GTR, previously had one big link at each depot, but some depots now have separate links (Cambridge is one - There is the Brighton link, and the Maidstone link who will maybe one day learn to Maidstone!). Hornsey has two links where there are route AND traction differences.
The GN side has historically lost drivers to LNER and the Thameslink side to East Midlands. West Anglia and Great Northern were one franchise as WAGN with the same pay and T&Cs, but since the GN merged with Thameslink (as First Capital Connect) the pay deals they've had over the years have brought changes to the flexibility of booking on/off times, with a taxi agreement initially brought in to aid in this, which has since been adjusted in the latest GTR pay deal to not include new drivers.
Sundays used to be all committed on the GN when it was WAGN, but the harmonisation with Thameslink under FCC made Sundays entirely voluntary for a time - which has now been changed to a commitment to work 12 per year.
Pay and annual leave entitlement also increased on the GN to harmonise with Thameslink under FCC.
Route and traction specific links have been now been introduced with the latest pay deal, doing away with a "facets of work to be shared as equally as possible," condition.
GTR and it's forerunners have basically always had a shortage of drivers which has never been caught up on as the service has increased each year. Factor in that drivers leave to do Intercity or even Continental work with other TOCs and Eurostar, good pay at Crossrail and the Overground, and to retain drivers during this critical period of the Thameslink programme a good pay offer was made.
Greater Anglia have competition for drivers with GTR and Cross Country at Cambridge. They did offer a large rise in a multi-year deal last year I think it was, but the drivers voted against it as they didn't like the changes to terms and conditions. I never did see what was on offer in any real detail, except that it included moving Sundays into the working week.
Funnily enough, one driver left GTR, taking a pay cut, to be at a GA depot nearer to home. However, he returned within 18 months as he didnt like it at all in comparison. Better management, better union representation, better work content, nicer route - just better all round, is his opinion. It was something he felt he had to give a try, as being nearer to home was desirable, but he's definitely happier at GTR.
SE are very far behind any other London TOC and falling behind nationally too.
South Eastern got a good deal a few years ago with a good rise which brought to an end the poor 'annualised hours' system they were on. I think it put them on a 4 day week as well.
It seemed to seek to stem the flow of inner suburban drivers jumping to London Overground.
Since then though, there seems to have been some stagnation in comparison to elsewhere.
