Just wonder if they would still be redundant if my employer the client had chosen to bring the previously contracted work in-house.
i've heard of services being 'in-housed' - as in formerly privatised / contracted functions being taken back in to (for example) local authority, and TUPE would apply there.
Not clear to me what is meant by " if your employer is insolvent but the organisation continues". The organisation certainly will continue but only in the sense that it is a crucial part of the business of the client ( my employer).
again, sounds a bit of a grey area.
how is the service being provided at the moment in the interim between old contractor going bust and new contract starting? is an administrator keeping the old business going? is it not happening at all? is it being provided piecemeal by a number of small contractors?
again, i'm not a lawyer, but the key question might be whether the old contract is continuing or whether there's a clear gap between old contractor ceasing trading and new contractor taking the work on.
my line of work is buses, and a few examples i can think of (although not been personally involved in the last specific)
operator A buys out operator B, or buys one depot from operator B - the staff at operator B (or that one depot) transfer under TUPE rights to operator A.
route X is re-tendered by Transport for London, and passes from operator A to operator B. Drivers who work wholly or mostly on route X are eligible for TUPE transfer to operator B. In practice, if operator A has vacancies, they will offer those drivers the chance to stay with them, but transfer to another route or maybe even another depot, but those drivers can still transfer to operator B with the route if they want.) Supervisors / engineering staff who work across the whole depot's operation would not be eligible for TUPE transfer, and might be at risk of a redundancy process if operator reduces the number of those roles. There have been one or two situations where a cross-London route has gone from an operator at one side of London to the other, and the distance between the two has been considered 'unreasonable' so redundancy has applied.
operator Z goes bust abruptly (as in the leasing company turn up one afternoon and want their buses back, drivers are contacted on the radio to bring buses back to the depot then bugger off) - no existing operator is in a position to take any of their routes on immediately, but a lot of different operators put a few buses out on those routes for a few weeks while TFL sorts the mess out and arranges new contracts. (this has happened) - in that case, the original drivers' employment with operator Z ended when they went bust and TUPE didn't apply.
From what you've said, this sounds more like an operator Z situation.
As things are at the moment (although will vary from one bit of the country to another) any driving jobs are having a staff shortage to a greater or lesser extent, whether that's HGV, van or bus / coach, so on one hand, the existing drivers will probably get redundancy pay and a new job relatively easily, although this will be on basis of having to apply for it, and on new employer's terms + conditions (although pay in most of these jobs is going up at the moment.)
from an operational point of view, risk is that the existing drivers will go and get jobs somewhere else before the new contract is sorted out, and new contractor may struggle to get enough staff for day one of new contract.
