Workers at Southern Rail have been offered a £2,000 lump sum to stop strikes going ahead.
Govia Thameslink, which owns the much-criticised train company, has set the RMT union a deadline of Thursday to agree to their offer, which includes further assurances to conductors.
The two sides have been in talks over a safety dispute.
The offer includes guarantees on conductors’ jobs until 2021, the life of GTR’s franchise agreement, above-inflation pay increases for the next two years and guaranteed levels of overtime.
Under the agreement conductors would migrate to a new on-board supervisor role, and those who take on the new role would receive a £2,000 lump sum payment in January.
The RMT Union recently announced a series of 14 strike dates from this month until December.
